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

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...

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.

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.

Bought the bigger 140 for my 30 gallon add says 30-50 for it but instructions even says its good for 20-30 and I agree. Tank is very clean and clear the skimmer part works awesome. Doesn't come with all the filter media so have to buy that extra if needed, I was able to use my media from my old filter which helped keep the good bacteria in and not have to start over for that. Definitely fully fill reservoir with water before turning on or will not work properly as it has a safety shut off incase of over heating or leak.
