  5. Reply CFerguson Sep 18,2013 4:03 am

    Julius – You can use more than one filter, just be aware of how much water turbulence you create by doing so. Too much water movement can harm fish, but the extra filtration offered may improve water quality and overall fish health as a result.

    I’ve had a Fluval canister filter for two years now, and within the last few months it’s begun to leak. I’ve greased the o-ring, and have ensured that everything is properly aligned. Unfortunately the first time the leak happened it damaged some hardwood. I now run the filter in a large bucket, which I have to empty daily. Obviously I’m in the market for a new filter now, and even though the Fluval comes with a three year warranty which is still valid for my 206, that hardly does my fish any good while the filter is out for service. Better than a warranty is simple reliability. Do a quick search for leak problems with Fluval’s and you’ll find many people with the same issue. I also checked into the Cascade 1000 above, and though I’ve not personally tested it, I’ve seen the same problems mentioned by others online that the Fluval has with leaking.

    I’m thinking about switching to a fluidized bed, has anyone tried one out?

    I’m thinking of setting up my 55 again and am trying to decide which is the best filter these days.

    Are under gravel filters a thing of the past? I’m not a big fan of them anyway, but I’m suspect of the biological filtration provided by canister filters. When it’s time to clean the canister filter, doesn;t that ruin the biological setup within and it just has to start over?

    How often do the canisters have to be cleaned?

    If I don’t use an undergravel then I should be able to have just enough gravel to cover the bottom of the tank, correct?

    Appreciate any input guys! Thank you!

    • Reply Dennis H. Oct 28,2013 9:20 pm

      Hey Scott,

      No, gravel filter are not things of the past, but you don’t have to use it if you don’t like it.

      How often to clean your filter media depends on how quickly it gets dirty. If your aquarium is heavily stocked and filter is less powerful you need to clean it even on weekly basis.

      I will suggest for you to buy a filter having intake of somewhere around 100 – 110 gallon per hour. And look for output water flow, if it decreases, it’s time to clean the filter.

      You can either use single powerful canister filter which may come hard on your pocket or if you are not using sand you can go ahead with a HOB filter along with a power head filter.

      Hope this helps. Cheers!

    I find that my eheim 350t works incredibly well in my planted aquarium, and gets rid if the need to put in an inline heater, or a heater in the tank. It has trays and trays of biological and mechanic filter media, and works for all kinds of freshwater aquariums. I’ve used many clip on, and external canister filters as well as in tank filters after 8 years of fishkeeping, and this is honestly the best I have ever used.

      Hi Keith,

      Use a canister filter or a sump, those are the better filtration methods to keep big fishes(which produce a lot of waste).

      Use a pump that moves up to 400 Gallons Per Hour(GPH), if you get a pump over those 400 GPH(Like 500 or 600 gph) is better, the bigger the better, but don’t exaggerate.

      Best wishes.

    I have a planted 75 gallon freshwater tank with many rainbowfish and a cranky old angelfish. I find getting into/out of canisters a little cumbersome, and time has become a bit more dear now that I have kids. So I run my old classic Eheim (165gph) with biological media+ an Aquaclear 70 (300gph) with 1 sponge and filter fluff in a bag. That way I get the benefits of a slower flow canister for bio (which doesn’t require much maintence and contact time is the key with bio filtration), and the ease of being able to change filter fluff weekly (takes only 2min- hence gets done routinely). With 30% water weekly water change my tank is crystal clear, and my nitrates are always <20 (usually <10). I can get weekly maintence done in 15 minutes! I am a fan of having 2 of anything, so if one device craps out u have the other going.

    I think a better representation of the “best filters” would include a voting poll of aquarists and not just your opinion.

      I have been using a two Fluval 406s for over a year and they are phenomenal. I have one on my 100 gallon community with some no name brand canister filter. The other is on my 55 gallon bichir tank. No problems what so ever. No loud noise and I have great filtration. Literally a week ago I thought my 406 on my community tank was rattling. I went to service the 406 and when I removed power the rattling did not stop. The air pump was rattling. But this caused me to look for a way to fix the noise. I came across this video and this was what I was going to try. I also have an eheim 2071 on my FH tank and it runs great too. I am debating between another eheim 2071 and fluval 406 to supplement my FH tank. I may stick with the eheim to keep the FH tank eheim and move the bichir fluval 406 go my community and sell the bichir. I have only ever had problems with off beat brand canister filters. Hope this helps.

    Fluval 406 should be renamed as a Super Duper Loud Fluval 406. This thing is really loud and i can’t believe myself that i actually fall in love with their marketing and misleading description. I owned 2 Eheim filters in the past and they were doing fine but i was greedy and wanted to get a better one with bigger capacity for biomedia, carbon bangs, different sponges and fine wool floss etc. So i made some research and read their description about 406 product as it is described as silent running filter etc. So i made a (rather stupid) decision and sold both of my used Eheim filters with a ridiculously cheap price on eBay and i bought the 406 and i massively regret after using this crappy filter. There are also tons of customers who have experienced this noise problem of 406. I tried so many ways to fix the problem but it does not work. My old Eheim products were much better than this new crappy fluval 406. will never buy again. never.

    I have a Fluval 306 that developed a leak after about 4 years at the hose coupling, actually at the swivel where the flow adjustment is. I figured i didnt trust repairing it so I replaced it with a new Fluval 306 since i figured it was cheaper than potentially replacing my floor. After about 3 months at its second disassembly for cleaning I found one of the small plastic tabs that holds the impeller cover on was missing. It obviously has broken off but I couldnt find it anywhere. I called Fluval amd was told i would have to purchase one. The only thing the 3 year warranty covers is the motor. So don’t be misled by what sounds like a good warranty. I expected better for a filter that was $150 or so.

The pump output is outstanding and anyone would be delighted in how this filter will circulate up to 245 gallons per hour.

    I am replacing 2 Aqua Clear 70 filters for my 125 gallon Amazon sevrum tank. These Aqua Clear filters are not very effective for the best filtration, because of the way the water flow through the system. Although the flow rate is very strong, the water going into the sponge filter media area seems to not move through the media very well. A really good HOB filter is Tetra Whisper. They seem to be much more effective keeping and cleaning my 55 gallon for water quality. I’m now going to a Sunsun canister 4 stage filter for my 125 gallon tank. This SunSun filter is powerful and silent. Moves 525 gph. You can load 4 types of filtration items in big trays. Under $100 and comes with a built in UV light. It has had great customer reviews. So far working great for me. Btw, I studied this filter for 3 years before purchasing it. Wanted to make sure people had owned it for a couple years before buying one myself.

    One type not mentioned here is the hamburg matten filter (HMF). Excellent option for those with tanks less than 75G and for fry tanks. There are videos on youtube showing how to make them.

  36. Reply DGG Jun 24,2015 12:49 am

    If you are wanting the best cleaners pick a cartridge filter that does not require “their” media or pads. HOB filters have such a limited biological filtering effect that they do little more than mechanically filter the water. Small tanks (30 gallons and under) can work OK with HOB filters and some secondary filter method like a UG. If you want the filter listed here that is best for your fish, its hands down the Cascade 1000. The GPH figure means virtually nothing. Each manufacturer lies about these figures and does their testing in best world scenarios which will never be your situation. Use filters that allow a good 1st stage mechanical filtration followed by a 2nd stage of biological filtration. Use a filter that allows you to use your own choice of media. Carbon is nearly useless in the filter world as is one of the biggest scams of the industry. You only need carbon if you are trying to remove medicine or plant tannins from the water. The best biological filter media you can put in a filter is BioHome Ultimate without any doubt. You have to order it online. And no I don’t work for them. I keep 18 tanks from 6 gallon all the way up to a 370 gallon and I can tell you this stuff is great. Of course the best filter is the one that is best for YOU. Cartridge filters with baskets are best for your fish but are not the easiest to clean. HOB filters are easy to clean but you pay gobs of money buying their cartridges to plug in which often aren’t more than a coarse sponge bag holding carbon.

      I also should have mentioned that if you have over 100 gallon tanks, ots time to do sump filtering. Sumps are noisy and require plumbing of tanks so I wouldn’t imagine too many people with under 100 gallons would want to go that route. But these are the best filters. Just not too applicable to the smaller tank aquarist.

      • Reply Photojames May 24,2018 1:51 pm

        Sump Filtration does not have to be noisy, it depends on how you set the sump up. I’ve been using sumps for years and found them no more noisy than regular aquarium filters. It just depends on how you set the flow up to the sump. I do agree for larger aquariums it is the best way to go. The initial set up is more involved, but the maintenance can be made much easier than a traditional canister filter.

I’ve only gotten noise during the initial start up. Every now and then I have to poke the spray bars but everything still keeps flowing as normal. I haven’t done a water changes since I set the tank up 4 years ago. I know I’m getting away with a lot, but being on sea duty wouldn’t allow me to take care of the aquarium the way I’ve done in the past, I also do see a need to interrupt something that seems to be working just fine.

    I dont normally leave comments but i feel compelled to save your marriage. For those looking for quiet filter, I recommend you to get aquaclear hang on filter. I got the aquaclear 30/150 and I’m amazed that there’s no sound at all. Not even the water sound. Nothing, nada. I thought that I’d here serenity from water fall from my filter but even the waterfall doesn’t have any sound. It is that good. I’m not exaggerating here. The filter is customizable and is super duper effective. Now I look at other brands of filter, I’m like “meh….”

    I have a big glass tank which is 4 * 2*2 it houses three giant guramee fish. The filtering system is a natural one which has porcelain cubes and some sponges. But the filtering system is literally useless as the tank is constantly discolored. Pleaae be kibd enough to suggest me a solution

    I have a 100l tank with a another 100l tank as a sump when I had a marine set up . Now I have a tropical tank and am using the sump as my filter , I am wondering if this is a good idea or if I should go back to a ext filter ?

    I purchased the Cascade 700 2 years ago.No problems until it started leaking. Changed the gaskets and replaced the canister and still leaks. Good luck getting support from Penn Plax. Left several messages and emails, no response and customer service only there 2 hours a day.

    Hey Dennis love your website and great post. I personally love anything from Fluval especially their canister filters. Right now I’m running a Fluval FX6 on my Cichlid tank. Couldn’t be happier, but the Fluval 406 (in your post) is also a great filter to use.

    I have an old MarineLand 350 that I have rebuilt from cheap parts ordered online. It works great on my 38 gal bowfront as a Marine solution. Now I have just broken it all down and am switching over to a Mbuna after so many years with salt. Will use it again to heavy stock an active community of Mbuna.

    I really love #5: AquaClear 110 Filter for my Aquarium. It is easy to set up, and keeps the water very clear.

    I’m sorry, but this list isn’t at all helpful. I’m new to this and am looking for a filter that won’t cost me $100+, I want a nice filter that is reliable, affordable and practical for someone who is new to the hobby.

    Aquarium filter is a must need equipment who like to put aquarium.

    The list don’t have any internal filter. Maybe you don’t like this filter type?

    I have a 120 gallon freshwater fish tank, under gravel filter ration system with two powerheads. Old school I guess, One of my powerheads needs a replacement impeller just wondering should I replace it or buy a new filter ration system something “new school “? What are your thoughts or suggestions, thanks in advance.

    I have had an Emperor 400 filter for around 13 years now and it works as good as the day I bought it. Marineland sells replaceable filter packs for ease and convenience but there are other options as cost well. The included 2 reusable grey media cartridges it comes with allow you to use low cost loose filter media such as activated carbon for chemical filtration. The unique bio wheels spin in and out of the water maximizing a healthy bacteria colony for biological filtration and never need replaced. For mechanical filtration I buy the bulk light bluebonded foam filter pads.The pads are cheap, easily to clean and can be reused many times over. The filter area even has extra slots for an additional 2 refillable media cartridges, sold separately, which can provide additional filter options if you have a crowded fish tank or just like to “over filter” your tank. Yep the Emperor 400 awesome!! I even had this filter in storage for a number of years as well in my garage in Phoenix with temperatures getting up to 120 degrees in the summer. When I decided to set my aquarium up again I was ready to buy a new filter but to my surprise the Emporer 400 primed up and went to work like a champ. I am currently using it for a 46 gallon freshwater full of tropicals, but if I ever go bigger than the 80 gallon recommended size I think I will just run 2 Emperor 400’s.

    API Filstar XP on a 55 Gallon freshwater tank has been the choice for me for the last 20 years. Easy to service and change out media and flawless operation. Wouldn’t even try another brand.

    I have kept fish most of my life. The best brand of filter that is easy to find and economical is Eheim with many choices for different sized tanks. I agree with Aquaclear for HOB

    Have had an Eheim Classic 2215 (now 350 I think) for well over 20yrs. Expensive but not in the long run. I have it paired with an Aquaclear 70 on a 75 gal tank. Highly recommended.
