Aquarium filters for large tanks are designed to remove waste and debris from the water, while also providing aeration and circulation. Filters help to create a healthy environment for your fish, and can also help to keep the water clear.
There are a variety of different types of filters available, and the best filter for your tank will depend on its size, the type of fish you have, and your personal preference.
20 Best Aquarium Filter For Large Tanks
1. Penn-Plax Cascade Canister Filter for Large Aquariums and Fish Tanks from 30 to 200 Gallons
Large capacily stackable media trays allow for multi-stage filtration.
Quick and easy push-button primer and two independent 360 degree rotating taps.
Flow rate shut-off valves adjust water flow and provide for easy maintainance.

I have now had 2 of these (a 500 and 700) and both have had a problem with the back side of the power head leaking, and the baskets do not have seals so water just goes around the edges unfiltered. You either have to create some type of seal (I have heard of using filter floss), or deal with a filter that doesn’t properly filter.
Regarding the leaks I do not see any cracks, and the seals seem alright, but they both leak pretty bad. At this point I have had multiple fish die because I don’t have a filter, my oak aquarium stand has been ruined by the water leakage and it has ruined part of my carpet as well.
They are both kept in containers and periodically checked to look for leaks. The leaks just come from nowhere and flood everywhere. I have also had the connector where the intake tube goes to the hose break and had to order replacements as well.
Spend the extra money and buy a better filter. Both my fish and axolotyls need new filters because these leak and don’t filter well. Reimbursement for the filters, damage and/or death and/or time would be greatly appreciated.
Bought as a replacement for a TopFin canister filter that cracked. Filter has a lot more flow than my old unit, even though they were both sized for a 60 gallon tank. I actually had to turn this one down.
The spray bar arrangement and return line fit the tank better and actually stay put. There is also an optional powerhead spout that can be used in place of the spray bar. Downside to this filter is that it is noisier than the TopFin.
It comes with activated charcoal instead of bio balls. The primer is a manual pump button. The only way to adjust the flow rate is to open/close the valves since the filter motor speed is non-adjustable.
The hoses that attach to the canister filter screw on instead of using quick releases. The instructions are pretty abysmal and lack a lot of detail. The secret to getting this canister filter primed is to make sure the spray bar is fully submerged.
It works good once you figure out that little detail which is missing from the instructions.
I got this filter because the dimensions fits my cabinet or else I would have got a Sunsun. This filter isn’t as expensive as Fluvals or inexpensive like Sunsun. It right in between. I have it on a 75 gallon.
It is very powerful and keeps the tank water very clean. The bad thing is that it isn’t as quiet as most canisters. I have a Sunsun and Eheim that are very quiet. The Penn Plex Cascade 1000 sounds like a large hang on the back filter, minus the water sound.
You can hear the humming coming from the motor. Sound similar to a refrigerator. Make sure to fill the filter with water, press the button a few times, and cut the tubes to size before plugging in the filter.
If the tubes aren’t cut to length and is long, the filter will not get a good siphon going, and may not start. Overall va very good filter. I just wish that it was more quiet. As I mostly purchased canisters for the quietness and sufficient.
The 50 Power Filter features a unique multi-stage filtration system that provides complete mechanical, chemical and biological filtration for your tank. This necessary piece of equipment is recommended for aquariums containing 20 to 50 gallons of water.
Your inhabitants thrive when the fish tank filter preserves beneficial bacteria that are good for growth, strength and stamina. This creates a stress-free environment for the maximum health of fish, other creatures and live vegetation.
The unique design of this unit creates a waterfall that flows silently into the tank, gently breaking the surface tension and creating beneficial oxygenation that moves down under the surface. The AquaClear 50 Power Filter contains a media basket to prevent water from simply bypassing your media and its benefits.
This superior contact time with bacteria maximizes the efficiency of the unit.
I have 2 of these Aquaclear 30 filters on an overstocked 20 gallon long. I set them on the lowest flow setting and they keep my tank perfect. One is an older version from when it still had Fluval name on the top, and a newer one after Hagen name replaced Fluval.
You can tell the plastic quality is not as nice now, compared to what it was, and also the top piece vibrates when it didn’t on the old filter. Not a big deal though. I’m guessing it is due to the cheaper quality plastic now being used.
The design stayed the same though, and the filter functions great. Easy to clean, easy to maintain, and seems to be dependable. I’ve read some complaints about these filters not restarting after a power outage but I’ve not had that problem.
As long as you have the proper water height in your tank and you keep the filter parts clean and clear of gunk it seems to start right up every time.
When I first decided to buy my red eared slider (turtle) a pet store set me up with supplies along with a filter. I’ve had the other filter for about a year and it just wasn’t doing the job. My water was constantly murky, even when I cleaned the tank once a week along with the filter! I was tired of seeing my turtle living in this condition and started researching for a new filter.
Some reviews under this filter on this website or other say, “it came broken”, “missing pieces” or “don’t buy, didn’t work”. That was not the case for me. The filter came with everything, including one back up intake in case it broke! After only 12 hours of the filter running, my tank has NEVER been so CLEAR! This filter is definitely a must.
I don’t usually write reviews, but after seeing the progress it’s done to my tank along with how happy my turtle is I couldn’t resist. I would 100% recommended this filter!.
A revolutionary bio-falls quad-filtration systemplus the polyfiber floss cartridge traps floating particulate matter. Activated carbon cartridge removes harmful chemicals, toxins, odors, discoloration and other contaminants.
Internal sponge optimizes colonization of beneficial aerobic bacteria and removes ammonia and nitrites, and external bio-falls wetdry biological booster for additional ammonia and nitrite removal and enhances oxygen exchange for maximum water oxygenation.
Quiet and efficient motor with adjustable flow control. Pumps 300 g. p. h. Polyfiber floss cartridge. Activated carbon cartridge internal sponge.
I’m very happy with this small filter in the 2. 5 months it’s been in constant operation. I have it on the back of a small 5-gallon tank that is on my office desk next to the desktop computer, so that while I’m waiting for videos or whatever, I can glance over at the tank; therefore, it’s imperative that the filter be very quiet and not a distraction.
This filter is so quiet in operation that I have to look at the filter box to see motion and know it’s working. There’s an adjustment knob to change the rate of operation, which is useful when feeding the fish.
The plastic filter box is a pretty blue color and quite roomy (6″ wide, 6″ high, 2. 5″ deep). I don’t use the carbon insert because I don’t believe in that form of filtration; instead, I replaced it with a nylon media bag full to the maximum of Biohome filter medium thus providing more surface for beneficial bacteria growth.
The filter intake wand is extendable to go deep into the tank to catch the debris at the bottom. The unit is relatively easy to clean. Finally, I like the fact that the filter motor is only 4 watts, so it’s energy-efficient, doing the job using little electricity!.
This is a very quiet self-priming filter. It doesn’t throw the fish around the tank because of the quad piece hanging over the waterfall. I changed the media to make it more economical to run. I replaced the biosponge with a 30 PPI sponge.
Then turned the sponge holder around to hold a cut to fit media pad. Charcoal is not necessary, but there are charcoal infused media pads available if you want it. The cartridge can be rebuilt by adding loose charcoal and sewing a media pad to it.
First, the description on the item is wrong — this item does not have the UV Sterilizer component to it. Unfortunately, I did not realize it before installing and running. Had I realized it, the item would have been returned — pronto.
So, now that the item is running it is woefully inadequate — surface space on the “filter” medium is small and will clog within hours, forcing the water over the lip by the intake siphon, effectively bypassing the filter cartridge.
The only good thing to be said about the unit is it’s quiet! Bottom line, don’t waste your money.
these work great use lift tube on one end connected to canister filter other end a power head or 2 power heads use corner filters for bio and chemipure or canister. i have had a tank that only needs filter maint.
and add water for over a year. shoot the flow direction of filter and powerhead at front center of tank to cross flow creating turbulent flow. other than monthly lite vacuming and keeping either the canister retun or powerhead above water at least.
5 inch for airation for amonia pretty maint free note use boyds chemipure.
I like the concept but I also run a basic 10 gallon filter that came with the tank. The tower/filter catches more of the air bubbles than gets into the water. The filter “towers” are a bit difficult attaching to the bottom filter.
This filter is ok, but not as good as my old one. The fish waste sits on top of the gravel; and accumulates on the edges of the tank. I have 6 fish in a 35 gallon tank; so I don’t have an overcrowded tank by no means.
SeaChem – Large Aquarium Fish Tank Filter, Tidal 110 Gallon (400 Liters) by Sicce Tidal Power Filters are designed from the ground up to provide your aquarium with high-quality, comprehensive filtration.
They are easy to use and adaptable to a variety of aquarium conditions. With a host of features including a self-priming pump, dual water intake with surface skimmer, adjustable flow, maintenance monitor, self-cleaning impeller, and a filter basket that holds any kind of filtration media – and more of it – Tidal Power Filters are designed to deliver the highest water quality possible with maximum versatility and ease of use.
They are suited to a wide variety of aquarium setups from saltwater to freshwater, ranging in size from 55 gallons to 110 gallons. Product Features Ventilation slots in the lid of the filter and aeration grooves in the outflow ensure that water returned to the tank is fully oxygenated and maximize gas exchange during filtration.
The pump pushes water up into the basket of the filter, entering through the bottom of the basket and being pushed out the top. A bottom-to-top flow ensures that water comes into contact will all filter media, and cannot go around or over filter media as with hang on back filters with a back-to-front flow.
The pump is also insulated and silent, making it excellent for office or dining room aquariums, and has extremely low power consumption for the amount of output. The basket is designed with raised slots which catch detritus rather than allowing it to fall through back into the filter when flow is stopped.
A heater can be attached to the side with an optional heater clip, allowing for better dispersal of heated water through the aquarium.
I can’t fault it ,they literally thought of everything. the pump is in the water so its very quiet , it has a pop up indicator to tell you if it needs cleaning , a large tray for media,you can remove the tray and it clips onto the lid so you dont spill water everywhere , you can adjust the intake and the flow ,you can remove the media basket without moving or switching off the filter and it self fills so if you have power outtage it will start up again with no problems.
there is a cable tidy and a holding clip you can attach to the side for a heater and it has a surface skimmer. the only thing that might be a problem is the intake,small fry would be sucked through the gaps but that can be solved by placing sponge inside the skimmer and sponge over the intake pipe.
Bought 2 of these for a new 75 gallon tank. Product is very very noisy, bypasses with anything but the sponge in it on full flow. Did I mention they are noisy & rattle like they are full of rocks? How noisy? I have to turn up TV to cover the rattling noise at full flow.
Even pulled impeller out, shaft axle is a very sloppy fit & probably has a lot to do with the rattling. Why no bushing or bearing where shaft passes through the plastic? Very cheap build! I lubed the very dry shaft & it was better for about 10 minutes, then back to noisy.
Right now, I have the output on both 75’s cranked down to 1/2 flow. Why would I buy 2 75’s that I’m turning down to a 55 or 35 just to use the bagged media it came with? Set at 1/2 flow, running the sponge & media it came with & the float is up- telling me time to clean! It’s brand new running on an empty tank that’s fishless cycling.
So disappointed. I also bought polishing pads for it too & more Seachem charcoal to run later- no way will that work! Wish I never bought it. I even did all the online hacks & those didn’t work. I guess I’m stuck with it now.
I have the Tidal 35 on a smaller tank & I can’t even hear it running sitting right next to it. Not the case with the 75’s. I can’t trust these 2 75 HOB’s cranked to half flow to keep up witha proposed African Cichlid tank now.
Aqueon QuietFlow Canister Filters comes with large media baskets, pre-loaded with media for all three stages of filtration: Foam Pads (mechanical), Carbon (chemical), Bio-Balls and Bio-Ceramic Rings (biological).
Designed for both fresh water and saltwater aquariums, the filter media can be arranged to fit any aquarium. Each filter comes with different return fixtures to choose from, traditional Water Director, Spray Bar and a unique hang on the back Polishing Unit.
The Polishing Unit allows for the use of one Large Aqueon Filter Cartridge to filter the water on final time before entering the aquarium. The cartridge is quick and easy, taking just a moment to do.
With three different size filters, for aquariums up to 155 gallons, Aqueon QuietFlow Canister Filters were developed by fish enthusiasts to satisfy the needs of fellow hobbyists and their fish tank needs.
Sorry I hate long reviews but there’s a lot to cover I’ve been running aquariums for over 25 years and have been disgusted with how difficult it is to buy anything without compromising something, they leak, their noisy, they only last a few years it seams.
My real problem is is noisy. This “Quite Flow” is anything but quiet. It has a rattle sound after just a week. I find it strange how every other company has a “quick release” were you just pull up a lever and pull both tubes out at once.
This so called “quick release” involves shutting the valve on each tube and then unscrewing both from the lid. That’s kind of a picky thing, but I was really not expecting to be less easy than my old Rena that I bought 15 years ago.
Next let’s talk about this hype over the back filter type water return. The thing is huge for what it needs to do. Inside is the cartridge filter is a joke, you can see right through it. The lid has no clips or snaps it just literally sets on top, and I can only imagine working on it and knocking that behind the tank.
It is so horribly designed it won’t fit any aquarium with hoods. I have glass hoods on my 55 gal and to add hoses or cords there’s a plastic on the back and you can just Dremel tool it out. Even if I took that off entirely off it still is too big, I would have to move my light forward and cut the glass.
Next, the tray’s have the intake tube running through them that need to be lined up. My old Rena simply flowed water down around the outside of the trays and then back up. I know a lot of filters use this method, these days.
The problem is the carbon comes in those cute little bags. Well when you put the bag in, there of course is no way to arrange arrange that to go around and to get behind the inlet tube, it leaves an area about an inch in wide on the side of the entire tray where there’s nothing.
Water flows through the least resistant place, I would think most of it would just by pass the bag of carbon, Next is the media that they give you. Upon unboxing they have bags of media in the tray’s.
I thought it was strange the order which they were in, upon reading the directions they are telling you completely the wrong way. First or bottom tray, they have the ceramic rings. Then the middle tray has a very thick fine pad, also in that tray comes a small pack of bio balls, that I guess your supposed to put on to of the foam.
WRONG! On top of that the instructions as it comes in the box tells the wrong way too. That you should be using the ceramic rings as the first layer, (bottom tray). NO that’s totally wrong, there should be a course pad followed by a fine pad then the media, then the carbon.
The instructions show 3 different set ups, none of them showing pads at all, and all show the ceramics on the bottom. There’s no course pad that even comes with it. And there’s no finishing pad on top.
I use those on top of the carbon before the lid goes on. They are expecting this back inlet thing with it’s horrid filter to be the finishing pad. If you choose not to use the back filter thingy it comes with nice tinted inlet and outlet tubes, and includes various exits.
It comes with the straight out with the direction plate. We’ll if you decide to use any of the other ones you need to get the one that’s on it off. This is held on with little plastic hooks that go over a lip in the tube.
There is no way to get that apart. I tried until if felt like my finger nails were going to get pulled off. So I got a small screw driver hoping to open at least on side. We’ll it broke right off, leaving one left and if that would break, that exit is useless, it wouldn’t stay on.
I just used the exit from my old filter. Finally there is no way that this flows 200gph. I have a power head right next to the outlet that is 160 and that flows way harder then this. Bottom line, I can’t say don’t buy it.
It seems like any new filter has problems, just make sure you put the media in the right order try to get a course foam for the bottom and please ditch the outlet box and last expect noise.
I NEVER write reviews so this should tell you how bad this filter is. I ordered this and setup wasn’t too difficult at first. I followed all the steps and before too long was ready to try it. It didn’t work.
After multiple attempts to get the water moving through the pump I finally got it going by pouring additional water down the in-tube The next day, I noticed the water level had dropped by about an inch.
I didn’t see any leaks (new tank) and didn’t feel any water or dampness. My miss. I filled the tank back to the proper height. Same thing next day. I refilled again, thinking it was just evaporating more than I was used to.
This time, after about an hour I heard dripping coming from the aquarium. Opened the cabinet to find a steady leak coming out the sides and the top. Nothing I had attached, it was all Aqueon! I was also well wishing the 4.
5 feet guideline between filter and water level. I’ve used Aqueon products for years but this is likely the first and last straw.
I really dont like doing reviews but I have to. Havent had a tank in a while so decided to go back into it. Went and purchased everything I needed. Was so excited about getting a tank again. Brought everything home cleaned everything, got tank set up and no fish for couple weeks.
Then I went and got a couple platys to help get the tank ready once I did went and got couple more. I have a 29 gal tank with Aqueon canister Filter 200 this is the worst filter I have ever seen. Suppose to be very quiet, it is not quiet at all, water constantly gushes out of filter.
Granted Aqueon did replace my filter but this one is no better, very noisy, gushing water our of filter. Cleaned the tank about a couple days before I got the new one and it needs it again, just dont feel like its working at all bt Iam havinh to make due.
The Penn Plax Penn Plax Undergravel Filter combines the function of a traditional filter while offering maximum viewing since its hidden out of sight. Designed for 40 to 50 gallon fish tanks, this undergravel filter uses mechanical, and biological filtration to filter harmful pollutants from your aquarium.
Undergravel filters create the most natural bacteria bed for fish tanks and provide effective aerobic filtration. Included are 4 filter plates (each measuring 11. 5 inch X 11. 5 inch) with extra large 1 inch adjustable lift tubes.
These lift tubes carry bubbles from the bottom of the aquarium to the top creating a gentle flow of water through the gravel and up the lift tube. Designed with narrow slat openings, the gravel is prevented from falling through to filter cartridge.
I have used these for over 45 years, and have no problems once my tanks are set up. The eco system created with these is the healthiest you can have. I have had tanks set up for over 10 years and not torn completely down.
If you do not have power heads, you can use the air lines and air stones inside the risers and they work just as well, but you have to have an air pump, that sometimes can get noisy. These are great as they snap together and stay in place.
Using the two to two and a half inches of gravel is essential. I do not know of anything negative about the system. I would recommend it to everyone, especially if just starting out with an aquarium.
Most people will start a tank up then change out water too often, not letting the eco system get built up. This is why many have trouble keeping the water clear and lose a lot of their fish.
This is by far the best filter that I have. I have had a few tanks, with all the filters now. In tank, over tank, and now the under gravel is tops to them all. The water is so much clearer, the fish seem much happier, and best of all, there is no need for all the wires everywhere.
The only down side I can see is that each air tube needs a separate air pump to get the right amount of pressure to keep the clean tank. That is a lot better then two filters hanging on the back or in the tank taking up space with the air line.
This only takes the air line. All three filters are taken in this one. BIO= the rocks on the bottom is collecting all the yuk stuff which is filtered out through the rocks removing all the extra stuff.
Natural= the air through the tubes. CHEMICAL = the charcoal at the end of the tube where the clean water comes out. This is to assure that the water is of good clean and yuk free for the fish to enjoy.
If you are a busy person, like me, this is the filter for you. Hook it up, feed the fish daily, and you are good to go for two weeks to four weeks. No more changing bags, or charcoal every other day, week, or whatever.
Hook it up, you are done and on the go once again. I would buy this again for any size tank from a one gallon Beta Tank, ot a 150 gallon professionaltank.
Cascade Canister Filters from Penn Plax offer heavy-duty multi-stage external filtration for your fresh or salt water aquarium. The Cascade 1500 Canister Filter can handle aquariums up to 200 gallons efficiently providing up to 350 gph of flow.
These filters allow you to combine the benefits of several types of media delivering powerful mechanical, chemical & biological filtration for crystal clear water in fresh or marine environments. Easy to install, these filters come with all the necessary accessories to connect to your tank and begin filtering in approximately 30 minutes and see visible improvement in less than a day! A quick push-button primer makes start-ups easy and the two independent directional 360-degree rotational valve taps make placement worry-free.
Flow-rate control valves and swimming pool-style hose clamps make setup and adjustment easy. The popular cobalt blue color will look attractive next to your tank and the sturdy rubber mounted tip-proof rubber base keeps the unit in place.
Each pump comes with large filter trays, start-up filter media & input/output tubing. The large filter trays mean you can use more media and have longer periods between replacement. An air-tight seal assures proper flow rate while maintain ultra quiet operation.
The easy-lift clamps make it simple to release the vacuum and remove the top for changing media or other maintenance. Directional returns help to suspend waste matter so it can be taken in by the filter leaving nothing but clear, clear water.
Use any combination of media including bio-floss, bio-sponges, activated carbon and others to accomplish a wide array of aquarium filtration needs.
I bought this filter to use as a gravel washing filter for my freshwater tank. It is extremely well made and works like a charm. I’ve read other reviews that complained about difficulty priming the unit but I usually fill it with tank water before starting and have not had any problem even thou I only use it to gravel wash.
However the unit is so well made and reliable, I would have used it as my primary filter if I was at all unhappy with my Seachem hang on back filter. I highly recommend this filter for tanks in the 20-30 gallon size.
All filters feature ‘flip-top’ access for quick and easy cartridge replacement. The U2-U4 models feature three-stage filtration for superior aquarium water quality and three way flow control with integrated spray bar for versatile water circulation.

Having had poor success with replacement external filters for my 200L tank, I purchased this internal filter and wowee! It is dead quiet and the water is crystal clear. Doesn’t do any damage to plants despite having two flow spouts.
What’s really great is that the slot design for the suction cups is improved so that the cups are fitted by pushing them into easy to fit slots instead of pressing them into holes. My cichlids seem to have a new lease of life as they’re swimming more vigorously.
Great product. Except the green spinning blades on the impeller assembly. Fluval won’t mail you just the 25cent replacement plastic. They sell the full magnetic impeller assembly for $17. A new filter costs ya $37.
Do the math – Fluval customer service sucks and they only care about selling more. Not helping their knowlegable customers with a quick easy repair option.
I have what is basically this filter, just the smaller versions, in 5 other aquariums. They filter well and have no more issues than any outside or canister filter. The fact that I can access them from the tank is a plus.
The water is clean and the output can be directed fairly well in a given direction. I do have to have 2, as they are in a 100 gallon tank, which is above the rating for one. Not cheap, but haven’t found an inexpensive filter that works.
The Cascade 300 Power Hang-On Filter quietly delivers crystal clear water throughout the aquarium. This filter pushes water at 300 gallons per hour (GPH) for tanks up to 100 Gallons in size. It’s great for Freshwater and Saltwater Aquariums.
Cant find one thing to knock on this filter. Super quiet and easy to put together. I would recommend taking the time to read the instructions that it came with but for the most part, its self explanatory.
I myself did not use the filters that it came with but rather bought some filter foam and cut it to the right size. Now I have a good filter and I never have to buy replacement filters for it. P. S. I did buy pre-filter sponges for it but its certainly is not required.
As the world’s best-selling performance canister filter, the 7th generation 07 series features Fluval’s eTEC (Efficient Technology) state-of-the-art materials and design refinements which make them ultra-quiet, powerful, energy efficient and user friendly for aquariums 10 to 100 US Gal.
(40-500 L). Fluval eTEC (Efficient Technology) construction employs cutting-edge design, materials & manufacturing methods to deliver powerful pump performance, reduced energy consumption & ultra-quiet operation.
Not worth the cost OR the gymnastics you have to perform to get into the canister. Pros: Relatively quiet as long as you have the canister located away from you. Cons: Top locking knobs pop off the canister easily but are practically impossible to pop back on.
Inner layers of the canister are awkward and messy to remove and place back in (locking arms to lift the canisters falls out of place and off way too easily) Despite the fx4 being overkill for my 125 gallon tank that only has 3 juvenile tinfoil barbs and a pleco, it doesn’t keep the tank crystal clear, and I have to dig into the canister almost weekly to change out the polishing pad because any debris in the polishing pad stifles the outflow of water down to a trickle and throws my tank cycle off.
Starting up the canister filter after cleaning the tank and changing even just the cleaning pad jettisons residual particles from the lines into the newly filled tank making it look dirty again. The particles eventually cycle out of the tank but add to the burden on the polishing pad and it’s a never ending cycle.
I’ve been struggling with this canister filter for 7 months thinking it would be a better alternative to hang on the back filters, but find myself wishing I would have just bought two of those for a fraction of the price of this canister filter.
Although Fluval customer service was very timely in responding to my questions, the only real solution they had was to purchase more of their brand liquid products to help with tank clarity (I had already informed them I use Seachem products).
For the price of this unit, and the continued cost of replacement medias internal to the canister itself, if the only solution to get the quality performance I wanted is to purchase even more Fluval products in addition to the unit, it’s a good indicator that the fx4 unit is not all it’s cracked up to be.
I have used fluval filters for Years , They never let Me down , I still have 2 Fluval C-3 filters that are still going strong after 4 years So I just upgraded from a 20 gal tank to a 40 gal tank , the old fluval 207 is just not going to cut it anymore.
, after 2 years of faithful service I needed to upgrade. And the 307 did not disappoint. Strong flow , so much so I had to dial down the flow. But that is the nice thing about Fluval, adjustable flow ! In case anyone is wondering the difference between the 207 and the 307 , obviously one is flow, the other is it has 2x the media capacity , the 407 has 4 instead of 3 baskets.
I highly recommend this filter , if You need help setting it up their are a ton of You tube vids available. This filter is highly customizable with what ever media You like. I get cut to fit rolls of floss and sponges to make my own at a fraction of the premade stuff.
Eheim or Fluval. The neverending debate. I wont settle this question. All I can tell you is the Fluval 407 is very quiet. It is easy to set up (although tubing is a bit stiff). For someone who wants inline co2 I would go for eheim as the tubing is not rippled and you wouldt have to hack your way around to install.
I run it in tank so not an issue for me. It is a powerful filter and very silent. It is in my room on a 90g tank and all I can hear are the hobs running in the living room 20 feet away. Maintenance is easy and for those who might still own a 404, there are many improvements.
The baskets are held by a long stick that goes trouvh them so that they can be removed all at once. The quality of the moving pieces ( in and outake shutoff; tubing holding pins; cover pins) are of better quality even though still plastic.
It is a great quality filter and should last for years.
Marina i160 Internal Power Filter The Marina i160 Internal power filter is a very smart and neat internal filter but very powerful and capable of filtering aquariums up to 160 litres. Safe for both tropical or cold-water goldfish tanks and clips securely onto the side of the aquarium with the powerful suction cups.
A fully submersed internal filter so extremely quiet. The Marina i160 filter also comes complete with 2 power cartridges which when needs replacing is effortless and mess free, only recommended to change every 4 to 6 weeks.
The power filter works by drawing water inside the unit and through the 2 power cartridges first. This special power cartridges designed to fit both the i110 and i160 power filters, helps remove pollutants and odours, removes toxic ammonia and captures floating debris.
To ensure the water is crystal clear. The marina i160 enhances aquarium water quality and is ideal for goldfish or tropical tanks. Overall it is quiet, compact and powerful. Bottom positioned motor for quiet operation and the waterfall spout for continuous oxygenation.
Bio screen provides large surface area for growth of friendly bacteria. Easy replacement of power cartridge.
This Marina i25 filtration system has really improved the water quality in my fish tank. It is quick and easy to set up and works within minutes at making the water clearer, cleaner and safer for my gold fish.
Buying this product has defiantly increased the life span of my fish and my fish has been swimming around the tank so much more than she did before. I am so pleased with this product. Not only is the price suitable but the size fits perfectly which is ideal for my fish tank.
100% thumbs up for Wilko’s Marina i25 Internal Filter.
I put it in my tank and the next day there was a rattling noise. Something inside the sealed unit had come loose. Now the water is just trickling out and definitely not working properly. As I have no box to return it in I’m stuck with it.
But definitely NOT SATISFIED with it. Certainly not worth 21.
I’ve had fish for years. It’s an expensive hobby to set up. This product was an excellent price at Wilko compared to other suppliers. It’s ideal for what I need for a fairly small tank. It quiet, compact and cleans the water well.
Marina i25 Internal Power Filter The Marina i25 Internal power filter is a very smart and neat internal filter but very powerful and capable of filtering aquariums up to 25 litres. Safe for both tropical or coldwater goldfish tanks and clips securely onto the side of the aquarium with the powerful suction cups.
A fully submersed internal filter so extremely quiet! The Marina i25 filter also comes complete with a power cartridge which when needs replacing is effortless and mess free (only recommended to change every 4 to 6 weeks).
The filter is designed to let water enter the centre of the cartridge for an effectrive mechanical, chemical and biological filtration process. Upon entering the second chamber the water goes through a zeolite chamber which absorbs toxic ammonia.
The 2nd chamber contains carbon so polishes the water and removes pollutants and odours. Any floating debris is trapped inside the cartidge. All to ensure the water is crystral clear!!!.
Key features include the patented Aquastop valve for an easy removal of the hoses, the hubverschlussklammern for easy cleaning and maintenance with a grip and several removable filter baskets, are already equipped with mechanical, chemical and biological media stuff.
Furthermore, the unique, square shapedFluval filter container space for 35-50% more water than round external filter with a comparable size. This provides for an excellent water flow through a complex cleaning process, a maximum contact time with the filter media.
Improved performance of the water filtering – generated cleaner, healthier water. With the addition of the bio-foam better biological filtering, medium. Noise absorbing impeller design for a quieter operation by 8 – 15%.
Newly constructed impeller cover, the less susceptible to cracking. Efficient intake system for easier operation. Reinforced Hub-Verschlussklammern for a safer closure. Hose lock nuts for more security.
Improved practical features, such as the aquastop valve, several filter baskets and the frame mounting, are now so easy to handle as never before. This text is machine translated.
This Fluval 206 Canister Filter is another in a series of “outside the tank” canister filters for aquariums. This model is distinguished from earlier models because of its design to be more leakproof than prior Fluval filters.
Most Fluval filters have 2 or 3 or 4 compartments which allow the use of various types of filter media to help keep the water as clean and pure as possible. The filter media consists of polishing pads, charcoal, and other various substances.
Experimentation leads to the best combination of the media. One nice feature is the ability to disconnect the filter for routine cleaning while leaving the hoses in place by the use of the connection on the top of the future.
It would be nice if Fluval would design a handle on the top of the filter to carry the filter from the tank to the sink for the maintenance. As such, always carry the filter by the bottom to avoid any damage to the filter canister.
It still requires attention at least monthly on average. As such, it is probably one of the best filters on the market for its purpose.
Paid top dollar for bottom of the barrel quality. There are two main chronic problems. First chronic problem is the water leak between the canister top and top motor unit cover O-ring. Poor design. It’s very touchy/finicky when reinstalling top to canister.
You will replace O-ring and even apply seal lubricant and experience leaks. The other chronic problem is the flow can significantly drop at anytime but more critically the flow will stop at anytime. You need to check out flow daily.
The top is hard to pull-off and reinstall but even with precise workmanship and patients, good luck. I keep a pan under pump and check it everyday when feeding.
I purchased the 406 in a desperate moment when my primary canister on my biggest tank quit and I had to rush to get filtration going again. My first impression of the fluval was that it was small for a 380 gph filter and i was concerned about surface area of mechanical media making the filter need to be cleaned more frequently.
Then I saw the hose kit it came with and was even more concerned. The hose it came with was ribbed for flexibility, and therefore the texture inside the hose will allow for significant debris to collect and be a real pain to clean, so I discarded the hoses and rigged some smooth clear hoses I had laying around to plumb the filter, which added considerable time to the set up process.
Even though the filter is physically small, I was able to fit a fair amount of biomedia into it. Once it was up and running the flow rate seems pretty decent for its advertised gph flow. Other things I found problematic is the valve block directs the hoses vertically out of the filter head, so even though the filter is physically smaller than my other canisters, it doesn’t fit as we under my cabinet and it took a little messing with to keep hoses from kinking.
I opened the filter up after it had run for a couple weeks just to see how clogged the filter pads were getting and was surprised at how clean they looked and decided that the filter should be okay to leave on the every 2-3 month cleaning cycle all my other canisters are on.
Ultimately the fluval 406 is a decent filter, but it’s over priced for what you get. Poor hoses, no spray bar, and the valve block routing hoses straight out of the top of the power head devalue this filter significantly.
The flow rate is not enough to properly handle the size of the tank it went on and I am currently waiting for another higher flow filter to arrive for the same tank. For a smaller tank, say 40g breeder, I think this filter would be sufficient by my personal standards (I want my tanks cycling 10x per hour at the bare minimum).
I will not be purchasing another fluval 406 as they are over priced for what you get. I might consider an FX4 or 6 when I get around to setting up an even larger tank though. Happy fish keeping!.
A trouble free biological filter designed with adjustable 1′′ dia. uplift tubes for better water circulation and multiple-plate construction for easy installation. Includes airline tubing and discard-A-Stone and features the fish-saver cleaning elbow.
Advanced design allows a separate plate installation and also has optional flow-thru set-up for use with a power head. Made of special quality plastic which resists splitting and cracking.
Good filter solution for 2. 5 gal aquariums. A lot better setup for individual guppy brood tanks than using a small breeder box. Plant the tank well for the new babies to hide. Remove the mother after she is through dropping babies.
Then raise the babies in this tank until they are large enough to be moved to a larger tank or the display tank.
I did not like that it came in multiple parts, but understand that makes it work in many shapes. I saw the other reviews about some of the slots being filled in. Lee’s must have fixed that. As to the reviews about clogging.
Use a colander when pre-rinsing your gravel. All the tiny chips and stones come out and do not clog your filter. This is what a colander looks like (picked that one because holes were most visible. ) Now Designs Metal Colander, 3-Quart, Turquoise A small mesh strainer in the drain is a good idea too (this one allows particles under it but you get the idea.
The dimensions are NOT as advertised. I have a 12″ x 48″ 55 Gallon Tank. This kit came with 3 plates – each measuring 14″ x 11. 375″. Well – 14 X 3 equals 42″. Yes, I understand the plates don’t have to go to the exact edge of the tank.
BUT being 6″ too short means I can’t “hide” the thick vertical tubes in the corners. Too bad the manufacturer doesn’t make plates more specific to my size tank. I will be returning these and getting another brand closer to my dimensions needed.
The EHEIM miniFLAT has adjustable output of 100-150l (26-40 gallons) per hour. Perfect for use in shallow aquariums or terrariums (requires a minimum water level of 1. 6 inches). It has an intake cover which protects the aquarium inhabitants and the pump.
Easy to clean, fully submersible and extremely quiet with low power consumption. Suction is on the bottom of the filter cartridge to protect the pump against running dry.
The 264 GPH multi-stage filtration system is ideal for fresh and saltwater aquariums ranging in size from 20 gallons to 75 gallons. The CF300 defies its low price because it comes equipped with all the necessary plumbing for installation and includes three large filtration media compartments allowing you to add the filtration media of your choice.
The filtration media trays offer a fully customized filtration system to suit your specific aquatic needs. The CF300 includes three fine filter pads (white) and a single coarse filter sponge (blue) for enhanced Mechanical Filtration.
With the addition of AquaTop’s Premium Activated Carbon, Ceramic Rings, or Bio-Balls (each sold separately), you’ll achieve superior filtration and crystal clear aquarium water. The CF300 canister filter has a convenient Prime Pump that eliminates the need for manual siphoning! Say good bye to a mouth full of aquarium water!!!.
Currently have 3 CF-500 to serve a 120, and 180. The only reason I bought these were due to the built in UV anf the price seemed be reasonable. One filter is about 3 years old and for the last 1. 5 years I have had issues with trying to reseal the plastic bar where the O-Ring resides.
I have also had issues with the plastic mount/clip where the tubing connects and had to buy another canister filter while I was shipped a replacement piece as it broke when I was doing regular maintenance on filter.
I will no longer by supporting this vendor as their product is made cheaply and isn’t made to last. Im tired of always having to try to fix something on the filter. After opening the cabinet this morning a pool of water sitting on the bottom of cherry cabinets for the last 2-3 weeks since when I did routine filter cleaning.
Now I have some water damage issues I will have to take care of. I would not recommend this filter if your looking for something to last 5-10 years.
Functional quiet filter which is easy to service but not very durable in regard to the filter baskets and pump head gasket. The plastic baskets eroded and started to break apart after only 18 months.
The pump head gasket started leaking after 3 years. The UV light burned out on year two when only used 2 weeks out of a month and the priming pump is now so stiff it is next to impossible to use. I added a top side filter will roller wheel to cut down the problem of surface protein filming which the pump failed to control.
I would caution first time users to place the canister in a large enough basin to capture the random unexpected water leaks which you may encounter.
This is a really nice filter, It went together semi ok. There could be more pics in the (manual) a folded piece of paper with a staple in the middle of it. But once you throw it aside, (The manual) and think logic you will do better.
No where in the (manual) does it mention the UV power switch. I found it quite by accident. It is under the clear dome on top of the filter. You do not need any thing else. It is ready to go. You may want extra ceramic rings.
The filter comes with some pretty cool bio balls, but there is room for more. and the more the better. A note: Not a prob, but I did not get a coarse filter pad. My unit came with only three fine pads.
Eheim Classic 250 External Aquarium Canister Filter; Put cleanliness first and protect your tank with the Classic 250 External Aquarium Canister Filter from Eheim. With this exceptional filtration system, you’ll get both mechanical and biological purification, constant water circulation and oxygen enrichment in one compact system.
It’s tested to ensure optimum efficiency! Already equipped with everything you need to get started—including detailed instructions—the Eheim Classic is one filter that gets the job done.
This is my first canister filter. I was bit put off by the reviews stating how hard this is to prime, but given the reputation of Eheim, I pulled the trigger. When I received the filter, it was straight forward to setup.
Cut the hose in half, cut off a 2 inch piece to go between the return pipe and the spray bar, cut where you want the shutoffs, slip onto the fittings, and screw it down. It actually takes longer to type the steps then to do them.
Priming is EASY. Put the suction side hose into the aquarium where you want it. Take the return side and suck on the hose just a bit to get the water to start flowing, gravity does the rest. The filter has been running for a few weeks now and no signs of leaks and very quiet.
Comes with everything needed including biological, chemical, and mechanical media. I love this filter and cant believe that I waited this long to move away from HOB.
yeah i should have bought an eheim canister filter years ago. but i now own 2 of them. this was the second one purchased (’cause i liked the first one so much). i love the simplicity of it. i’ve used aqua-clear 70’s & 110’s for years, which are still great and i still use them on the smaller tanks, cause they break down for easy cleaning.
but this canister is as easy as it gets. and it came with lots of media(coarse foam pad, fine foam pad, pre-filter ceramic, bio-ceramic, and a carbon pad) and the quick shut off valves. it also had all the hose you need and a spray bar.
It’s virtually silent while operating(aquaclears get noisy at times). I love both of my new eheim canister filters and I’ll be getting a third! Highly recommended.
I bought this for my 75 gallon planted aquarium based on Eheim’s reputation for quality. I was replacing a less expensive (but much more user friendly) canister filter that developed a leak that I was unable to fix.
A leaking canister filter is the death of a hardwood floor, so reviews stating that the Ehiem was the least leak-prone option was the deciding factor. This filter costs three times what other similar capacity canister filters cost, so my expectations were high.
The gasket on the lid is a silicone ring, not a rubber band, so hopefully it will last a long time. On the plus side, the filter is very quiet. On the minus side, there are virtually no instructions for assembling, installing, and starting this thing.
The instruction booklet is huge – but it gives a tiny bit of information in many, many, many languages. I ended up watching a bunch of YouTube videos on how to set it up, prime it, and get it running.
The hose provided (1 piece, you have to guess how to cut it up to use it to connect all the pieces together) was barely long enough to accommodate my setup (tank on a standard cabinet stand with holes in the back for hoses to run through).
The spray wand is only 12″ long. How you would think a 12″ spray wand would evenly circulate a 48″ long aquarium, I have no idea. (The previous filter had a 36″ spray wand, which moved water throughout every nook and cranny in my heavily planted tank.
) I extended the spray wand a little with a longer piece of the tubing than recommended in the videos, which almost, but not quite, got the spray wand to the center of the tank. The hoses and tubes are all this intense green – they look pretty ugly.
Why not black so they disappear? There is no priming pump; you have to go old school and suck on the end of the hose to get it started. Yuck. Fortunately it primed quickly on the first attempt. Overall, this filter seems very overpriced for the features (or lack thereof).
It can only redeem itself by keeping my hardwood floor dry.
Effective filtration provides the ideal conditions for your aquarium fish, plants and coral to thrive. With its unique, easily located cradle the filters are simple to fit. The PF range features a triple stage filtration system with mechanical, chemical and biological filtration.
The PF2 provides effective aeration with rocker switch controlled powerful venturi. Its low maintenance design features an easy to clean cartridge. The patented aqua valve is a non-return valve that prevents waste from being dumped back into the aquarium when the filter is removed.
The PF2 is fully adjustable, with easy flow rate and direction adjustment. The PF2 is ideal for aquariums up to 60cm (24”) in length and from 45-90 litres (10-20 gallons) in volume. It has a maximum flow rate of 500 litres per hour (110 gallons per hour) and is 9 Watts.
PF Filters are available in 5 sizes. Replacement filter media for this product are product is for animal use only and should under no circumstances be administered to any animal other than that which is stated for.
The PF2 I inherited 20 years ago had started to turn on & off like it was on thermostat because the impeller seatings have worn. The PF2 was out of stock and so i looked at the spec for the PF1 to find that it will cope with my 2x1x1 foot tank.
What a mistake. My unused PF2 carbon filters dont fit the PF1 design, even when cut down to size, and the carbon filter provided has the plain filter stuck to it, so you have to throw away the carbon filter when to throw away the plain filter! The PF1 has no biomedia cage and the ceramic rings are in a mesh bag that takes up the space that the plain filter should occupy.
So, if you have a tank of under 90 litres, I would buy the PF2, as at least it has ap roper biomedia cage above the filter holder, and then youll be able to fit separate carbon and plain filters, and change them at a different frequency.
The mini is perfect for my daughters 17L tank. Love the directional nozzle so you can make the water shoot upwards and make so nice air bubbles. Very quite pump too. It did cause some vibrations with the lid but soon cured that with some foam draught excluder round the top lip of the glass.
I find this filter great, 4 types of filter media to keep your tank clean. I don’t have a problem with the filter being noisy, even using the venturi for bubbles. Great product at great price. Would recommend.
Max. The polluted aquarium water is cleaned using a five-step process and a variety of different filter media. The water is passed through ceramic filter rings, bio filter balls, traditional filter foam, carbon filter media and filter floss to remove the various dirt particles and provide biological, mechanical and chemical filtration.
The practical handles on the individual filter cartridges make it easy to clean the filter and replace the filter media, and the outflow pipe and hose can be adjusted to suit the size of the aquarium without any difficulty.
There are also control valves on the inlet and outlet pipes to accurately set the flow of water and adapt it to suit different requirements. For cleaning purposes, simply shut off the valves entirely and remove the filter unit from the connection equipment.
The column of water is retained to ensure that there is no need to repeat the suction process when reconnecting the device. Depending on the level of pollution and wear and tear, the filter media should be replaced approximately every 6-12 months.
Nice filter, but like all filters they are only as good as the media that is in them and how you set them up. Dont take too much notice of the manufactures flow claims as you can pretty much halve the claims for most of them by the time the media is installed.
Also dont take too much notice of how the trays come as they are usually wrong. Always set filter up so the first tray contains the course, medium and fine sponges which leaves the others free for your media.
The last one should be for carbon if you use it. If none of this makes sense see pondguru on YouTube!.
