Customers say
Customers find the filter effective for small tanks, particularly 3.5 gallon betta tanks, and appreciate its quiet operation and excellent water flow for betta tanks. Moreover, they consider it good value for money and praise its cleaning capabilities, requiring frequent filter assembly cleaning. However, the functionality receives mixed feedback, with some reporting it stopped working for no apparent reason. Additionally, durability is a concern as units break within 45 days, and water clarity results are mixed, with some reporting clear water while others experience murky conditions.

Small But Mighty for 3-Gallon Tanks
f youâve got a 3-gallon tank and need a reliable, compact filter, the Aqueon QuietFlow E Internal Power Filter Extra Small is a little powerhouse. This filter may be small, but it delivers great filtration without taking over your tank space, keeping your water crystal clear with minimal effort.Performance and Filtration:For its size, the filtration power is impressive. This filter offers three-stage filtrationâmechanical, chemical, and biologicalâso itâs keeping your tank fresh and clear. It efficiently pulls debris, uneaten food, and other particles out of the water while keeping it oxygenated. The water flow isnât too strong either, which is a relief for smaller tanks where some fish can get stressed from strong currents. Itâs just enough to keep things moving, without turning the tank into a whirlpool.Quiet Operation:One of the best features of this Aqueon filter is the quiet operation. You hardly hear it running, which is a big plus if your tank is in a quiet room or bedroom. Itâs aptly named âQuietFlowâ for a reasonâit wonât disrupt the peaceful ambiance of your aquarium setup or your sleep.Size and Setup:The extra-small size is perfect for limited space and small tanks. Itâs designed to hang on the side, so it doesnât take up much interior space, giving your fish more room to swim freely. Setting it up is quick and easy, and it works right out of the boxâjust plug it in, and youâre good to go. The filter cartridge is easy to replace too, making maintenance simple.Pros:Compact and unobtrusive, perfect for small tanks up to 3 gallonsEffective three-stage filtration for clear, healthy waterExtremely quiet, ideal for bedrooms or quiet roomsEasy setup and low-maintenance with quick cartridge changesCons:Best for light bioload tanks; may struggle in heavily stocked tanksThe flow rate isnât adjustable, so it may be too strong for very delicate fish or shrimpCartridges need regular replacement, which adds a bit to the ongoing costPro Tip:If youâre using this filter for delicate or small fish, consider adding a pre-filter sponge to reduce the water intake strength and provide even gentler filtration.Bottom Line:The Aqueon QuietFlow E Internal Power Filter is a fantastic choice for small tanks up to 3 gallons. Itâs reliable, quiet, and does a great job keeping the water clear without taking up too much space. Perfect for anyone looking to maintain a peaceful, low-maintenance setup in a smaller aquarium. If you need efficient filtration in a compact, whisper-quiet package, this little filter is worth it.

Totally worth itâ quiet, efficient, and hassle-free installation.
Compared to the filter that came with my tank, this product is magnificent.The filter that came with my tank was an air pump filter, it was loud and made some really strange and scary noises sometimes, it was clearly very cheap. I used it for maybe a year before it just stopped working entirely. It was overall a poor design for a filter. I tried other filters but they all ended up being too big for my 3 gallon tank.This filter however is so quiet, itâs bigger than my last filter but conveniently still fit in the same spot my old filter was and doesnât disturb the top piece meant to cover the top of the tank. I simply inserted the hook pieces versus the extra suction cups and swapped out my filter with no hassle or mess. The hooks do make the filter sit up higher but again it conveniently fit so perfect that the water is spilled right back into the tank and not on the top cover, sides, or back. Depending on your tank construction, it will depend whether or not you use the hooks or suction cups, which in my opinion I found convenient that they provided both pieces for that option of flexibility. This filter does produce a bit of a stronger current than my last filter so my betta struggles if he is right under the current, but I think he will adapt and be just fine. Overall great buy, and it wasnât as expensive as other filters I was looking at.

Stopped working altogether after 2 and a half months.
Newest and Last update as of September 7th, 2021:I bought this item June 16th, 2021. It stopped working a week ago. I took good care of it, hoping to beat the odds with all the other bad reviews saying it stopped working a month or two in. But they were right. Listen to those reviews. Money is tight for most people right now. Do not waste $$ on this.-_-‘(Old) Update: I’ve had this filter for almost a month. I decided to keep using it (whenever I was out of the room and not trying to sleep) as a backup filter. It has kept my water quite clear. Very recently I noticed it seems to have become quieter to the point where I could stand being in the same room while it is running. I dont know if anything is wrong with it, or if it somehow needed a bit of time to be broken in, so to speak. But I am grateful for the lesser noise, so I’m raising my 2 stars to 3. I might be back one day to update on its longevity.(Older) Previous review:I read quite a few reviews saying the 3 gallon filter was so quiet that they can barely hear it running. That is not the case for me. It is far too loud for me to ignore and I’m positive I wont get used to it. The sound also reverberates around the room. I believe there are better products out there for the same price or less. I bought a Tetra internal power filter last year that’s at least half as loud as this one, if not less than half. I have had the filter for just a day, but I need it to be quiet. It filters well enough for my 3 gallon tank that contains 15 ramshorns, although it took about a day for it to clear the slightly cloudy water I had. A positive is that I have the filter a bit higher up above the water level to create more surface agitation, and the trickle of water is still barely ever heard at a small distance. So…quiet “flow”, yes. Quiet filter, nein

Works great but only for a few months
This little filter has been great for my 3 gallon tank but Iâve bought two and each has only lasted about 6-8 months. For the price this is still worth it to me, but be aware when buying.*Edit after buying my 3rd one – The last power filter only lasted 5 months, but again it’s worth the $13 to me.*

I’m using the 3 gallon model for my 5.5 gallon tank. This product cleared my cloudy water within an hour! Super gentle flow which is great for a betta. Super quiet too, I can’t even hear it! Love that it has suction cups, since my rim was too thick for the hanging tabs. Doesn’t bother my curious betta at all, he seems to like it and is playing with it by swimming back and forth under the bottom (pics attached). I read a review that a fish got stuck behind it, so if your fish is smaller, maybe put a bit of sponge in the gap to be safe. I would highly recommend this product.Also, for anyone wondering… yes, it’s a wine glass, and for some reason, his favourite thing
