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

Great value for excellent filtration. Look, canister filters are expensive but so are fish, and so if you want a great value filter that does a good job, is reliable, and easy to install (well, for a canister filter--we all know they are a pain), this is a good fit. I have one for my 50 gallon and I would totally get another if the need arose. I have a fancy Fluval that cost three times as much in another tank and I can't say there is much difference in function, although it is a little bit easier to set up the Fluval than this one.

I was going to get a more expensive fluval a filter but after research I came to the conclusion that they are all probably similar or the same and this one has the UV light. I would have had to pay more money for a trusted name brand one when this one does the same thing and more for less money.4 stars for suction power because I did feel like I had a really hard time starting it. The hand pump worked to an extent but I had to pump it a lot and very quickly to get it to start functioning and it hurt my knuckles a few times.The tubing that comes with the filter is a little flimsy but if you follow the advice of boiling it to work out the kinks, it does sort of fix it. I currently have it hooked up with the original tubing but I did go ahead and invest in some new tubing of sturdier quality. The new tubing was pretty inexpensive so it is not a complaint. The seller also offered to refund/reimburse me for the tubing that I bought.My overall review on this product would be 4.5 Stars. It's pretty easy to take apart and put together.

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.

Very quiet. Almost can't hear it. Took me 5 hours to get it to work, but this was not the fault of the product. I didn't realize I had the inlet and outlet swapped, which kept it from flowing. Once I swapped those it works flawless. For anybody who cannot get the system to prime, heres how I did it. Start with and empty canister (no water). Connect your inlet tube to canister. Go ahead and run inlet to the tank where you will have it positioned. Then connect the outlet tube to the canister, and run the tube into a bucket on the floor. Close the valves on the canister. Open the cap on the top of the inlet that you mounted on the tank. Fill the inlet tube thru that hole, until the tube is full of water. Once full, open the valves on the canister, you will hear the canister filling with water. Wait patiently as the canister fills. Water will eventually run thru the outlet tube and into the bucket. Once it runs smoothly into the bucket without blowing air out, shut the valves off again. Now mount your outlet onto the tank. Keep this above the water level. Now plug your canister filter in and watch as all your hard work pays off. I hope this helps someone as the instructions suck and the manual primer on the canister is absolute trash.

This filter is underrated. I've been using it for over a year now for my juvenile snapping turtle—who is a messy eater and poops a lot—and this filter keeps his water crystal clear all the time. It has also handled the bioload from a bunch of guppies that keep reproducing, since my turtle has decided that fish are friends, not food.I appreciate that the filter isn't the size of a garbage can like the Fluval, and there's plenty of space to fill it with various types of filter media. I also find it easier to clean than the hang-on-back (HOB) filters I use in my other aquariums. I simply take it out to the side of the house, rinse everything with a hose, refill it, plug the hoses back in, and it's good to go for several months.It's virtually silent—the bubbler in the tank is much louder. I was initially concerned it wouldn't be able to keep up with my turtle, but I couldn't justify the cost of the Fluval when this one is a third of the price and has a higher GPM (gallons per minute) rating. While I’m sure the UV output has degraded over time, the light is still functional.
