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

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.

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.

Purchase this filter system in November 2022.The prime pump handle disintegrated into pieces in February, just days after the return window closed. One month later March 2023, the machine is no longer producing clear water. I have a bacteria outbreak as a result of this. All new media was used in the last cleaning process, and the system was washed as directed as usual. Did not stop it from having particles and algae blooms producing from the filtration system itself. Three just assemblies and three re-assemblies and cleanings and replacement of medias. Again, I finally get it to produce clear water. as time is going on, and these repeated cleanings that had to take place, the machine is physically, wearing fast cracks are developing on the fasteners, and the prime pump is further disintegrating with the post reducing down to a nub. April 2023. I woke one morning in my bedroom to find the laminate wood flooring bubbled all the way across the floor. I immediately assumed it was a exterior underground leak from the sprinkler system outside, but I was wrong. As I entered my dining area, I noticed the fish tank was down about 3 inches in water. That’s right this piece of crap destructive machinery that wasted my $140 plus all the extra media I had to spend out for when it started to malfunction and not properly filter. The system, has now incurred the cost of replacing my bedroom flooring, not to mention the wall between the dining room, and the bedroom . The canister was leaking from the seal line all the way around the top of the canister with water coming out from the prime post area primarily. So I believe the water is leaking out of the pot, prime post down into the top of the canister where the motor is and just leaking out the sides down through the latch locks . So 4 inches of water in a 55 gallon tank that math I don’t know how to do to estimate how many gallons came out that I would I would guesstimate at least 10 to 15 gallons of water. The return window has closed in January and I am simply going to cut my losses and move onto a different brand. Amosijoy has lost my confidence as a consumer looking for a reliable product. A properly working filtration system is one thing I seek, but any further problems in my life such as thousands of dollars of floor and wall repairs is unacceptable . I will never buy another product of theirs, and I highly advise anyone seeking for filtration products to overlook this brand and to move on to other reputable sources.

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.

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.

Good quality, still works good. A bit challenging to clean the conmecting tubes,I wish it would have some cleaning tool coming with it. Otherwise great

100% recomendable Cumple con las expectativas, buena relación precio calidad. Tiene mucha potencia, ahora solo esperar cuanto dure ya que llevo solo unos días con el.
