AMOSIJOY 172GPH Canister Filter, Ultra-Quiet External Aquarium Filter with Free Media for Large Fish Tanks and Aquariums (172GPH)

Returned as I ordered wrong unit, unfair to give negative score

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.

I purchased this for a 20 gallon tank to help with cloudy water from algae as my little Aqueon filter couldn't hack it. I took it out of the box and whoa, it's a beast! I thought maybe it was going to be too much filter for the tank, I was wrong, it's a great size. The canister itself goes together very nicely and both inlet and return connectors are clearly marked and very strong. The hoses are beefy and very stiff, which is the only troubling issue that I'm dealing with. The very simple and small instruction pamphlet suggests to soak the hoses in warm water to make them more pliable. I did this, it worked ok, until the hoses got back to RT. The tube sizes are quite large and the tank lid does not sit flush. I belive I will change to a tank mounted light rather than a top. I've found the intake tube to be very long and is sitting at the bottom of the tank, I'm not really a fan of that, but so far it seems alright. Priming... well, the priming pump on the canister is smooth and has decent suction unless there is a lot of air in the canister, and this made priming the tubes quite frustrating. I'm not an expert, fairly new at keeping fish, and I've always used a hang on the side filter, so this was a new method of filtration. It took me about 15-20 minutes to get the tubes properly primed and full, how I did it still not sure, but when it happened, outflow was nice and steady. The instructions did not have any suggestions or methods to make it easier, and as a new user of a canister filter, I would have liked to have had that. I'll have to make some adjustments with the tubes but that's a minor inconvenience. This filter is definitely worth the money, you shouldn't be disappointed.

We bought this about a month ago and it arrived in great condition. It took us about 30 minutes to set it up because we are new to canister filters but now that we know I think it takes less than 10 minutes to set up. Getting it to start pumping the water was a little difficult. I think it was due to how low we have our aquarium but once it started there was no stopping it! It came with bio-balls and a sponge that we literally just threw in along with some ceramic rings we kept in the previous waterfall filter and let it rip! It has been working perfectly keeping the water crystal clear. We've never had an aquarium so clean without having to do anything! We've done the water changes just because it feels wrong not to do them but honestly, we test the water weekly and it is always within parameters. It is so silent that the only thing we hear is the air pump sitting on the other side of the aquarium. The value you get for the price you pay is awesome. Recommended for newbies, you'll appreciate your hobby a lot more and will keep your fishies super happy.

This filter is quieter and works more efficiently than a filter I paid almost three times as much for. The light is incredible at keeping the water crystal clear. It’s easy to maintain . The light kills all bacteria both bad and good so there’s no point in using any bio starters in the water. My fish are very happy.
