AMOSIJOY Canister Filter, Ultra-Quiet External Aquarium Filter with Free Media for Large Fish Tanks and Aquariums

I'm glad there's some cheap canister filters on the market. Thing is quiet and effective, I got it running on a 20G long at about 1/4 flow rate. Very nice the flow rate is adjustable. I didn't even take note of the included UV operation, I probably will not enable it unless necessary. Designed well, easy to clean. However the trays have a silly shape so cutting custom foam was tedious, but doable. I didn't expect it to come with media, the media it comes with should be discarded and replaced with actual sponges... While it comes with intake/outake lily systems, and the unscrewable part to fill the line makes priming a breeze. It is just cheap plastic, doesn't look too bad but consider getting your own lily tubes if you care about aesthetics. I also had to cut down the intake tube significantly to fit in my tank, which is fine. Better for everyone that it can be super long for larger tanks. Drilled some holes in the pipe and installed an intake filter, which I highly recommend to save fry/shrimp and also minimize maintenance. Overall great deal. First one I got wasn't working but turns out it was my fault, got greedy and tried to use the upper section as an additional media compartment and it blocked up the outflow mechanism... so be careful about that. Second one working great.

This seems to be doing quite a good job in my tank due to the fact that it pushes so much water through. I have purchased in tank pumps and they just didn't perform like they needed to. He always needed to have them cleaned/removed slash a pain in the butt. This thing has worked for a month and I'll be cleaning it sometime soon but as far as I'm concerned it is definitely better than the in-tank pumps... Less cleaning and better circulation of the water. I recommend this or I think there's like one or two higher than this. I don't recommend the lowest choice that they have this one is like number two on the list. Anyway, it's during the job and I think you'll be happy with it. Keep the tank above the pump the gravity of the water will help it not to stop pumping That's a must. The light should be stronger but it does what it does. I would enjoyed it more if it had a higher wattage for the UV light. Haven't had to clean the pump for the last 30 days which is so much better than in tank pumps I was having to clean those almost on a weekly basis if not twice a week. The amount of water this thing pushes through is good and does its job. Recommended. Update: The pump stopped working and is going back to Amazon. I'm opting for the next size up which I shouldn't have to because the tank is only about 15 to 20 gallons. However, I'm hoping the quality of the next size up will fix the issue with a stronger flow. I've lost quite a few fish due to the pump stopping and the heater overheating the tank due to lack of flow. This will be the third attempt. The first one was sent back because it never worked / the replacement worked for about 3 weeks and we shall see what the third one will do. It's got 30 days to impress or it will go back as well and with that I will switch to another brand. Hopefully, the extra power in the size up will allow it to function correctly and keep flowing instead of sitting there like a brick not doing anything. Will update...

Canister filter worked great on timer for two weeks. So it was not on 24/ 7. Then it stopped taking water into tube intake tube that pulled water from tank into canister. It no longer has power to suck up water into the unit for cleaning tank water. Tried disassemblying to remove any debri that might hinder moving parts... it worked for for maybe an hour and then found it stopped once again. this time off the timer system. So... I'm out the $$ and back to long hours of manual tank cleaning after many wasted hours trying to get this to work.

Purchased this in February 2025 so I’ve been running it for almost a year. The filter has been working amazingly. I have the 225GPH version and run it on a 8 gallon nano tank. Perhaps some people will say it is overkill but I have not had to do a water change (only top ups) for a year and have only cleaned the filter sponge once. Not sure how effective the UV bulb is but algae has been minimal. Water is crystal clear 24/7. The stocking in my tank is very light and it is well planted. 1 Male guppy, around 30 neocaridina blue shrimp, and maybe 10-20 rams horn snails. I would definitely buy this filter again for another tank this size or even slightly larger. Very easy to clean if needed, you can close off your intake and outflow tubing with one lever. I love the adjustment for water flow as well. Noise is very low as well, my air pump is much louder. Fits nicely inside an aquarium stand cabinet.

No complaints so far. The self primer works ok and the filter is pretty quiet once the air settles out of it. Didn't use the provided out/intake. Hooked up just fine to 17mm glass lily pipes. The adjustable flow is nice, we'll see how that affects the rotor long-term. Didn't use the plastic balls it came with and replaced with ceramic media I had. The UV came just fine, not sure how often if at all I'll use it but nice to have I guess. Overall, pleased to with the performance-to-price. May update in a few months to a year. We'll see. Update from 10/06/2023: The filter has been chugging for almost 1.5 years now, everything is still going strong except the self-priming handle broke in the last month or so while I was repairing after a water change. The little handle that flips up to let you pull on the priming but is made of plastic and clips into both sides of the flat end piece on the priming piston. That part being broken makes it very hard to prime. If that didn't happen though, it would be still going strong. No leaks and not noisy so long as you don't have an intake that sucks in air (pipes with a skimmer). For the price, I can't really complain.

great little canister filter really seems to move more water per hour than advertised but have not been able to measure that really. had a light go out in one of them but it came with an extra light and it was easy to install.

So far, it’s great! It’s been 24 hours running, everything works, no leaks, SUPER quiet. I can hear my cats water fountain over the pump. Very easy set-up. Can’t say much about durability or quality yet. I’m letting it cycle and building bacteria before I transfer my fish. The length of tubes provided was plenty long enough.

it’s a OK filter I used it on my 60 gallon breeder tank and it did not meet the expectation. It would be perfect for a 40 gallon aquarium whatever size filter you buy make sure you Aquarium is a lot smaller. And the pads they give are cheap and useless

No it is not a UK plug but I brought a power deductor for this, so it can be used in the UK. Know it's all up and running, wow what a Filter my tank has never been so clean and clear,even the fish are happier

Do not buy one of these. Silent operating, yes because they do not work. This has spluttered a couple of times but is pumping and filtering no water. Having had canister filters before decided to go back to one again. So now I am going to have to make a trip out to an aquarium store today to buy a replacement so my fish do not die. Once again do not buy this I have a lot of money for something that does not work.

Initially, I didn't feel entirely confident upon observing the seal design, and that sentiment persists. It's not due to any immediate problem, but rather a concern that with time, the latches may weaken, potentially leading to a leak. However, there's a chance this may not occur. Currently, everything seems to be functioning as intended, and the UV light indicator is still active.

It’s not working well a

Works amazing! Better than expected for the price
