AMOSIJOY 172GPH Ultra-Quiet External Aquarium Filter

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.

My 40 gallon aquarium became a headache to clean and keep it clean, no matter what I did the water was never clear. Once I installed this 3 stages filter, it took 24 running the UV light and 2 days later my water is crystal clear. The installation was super easy. My aquarium has happy fish and no obstructions with bulky filters. It is now a piece of art in my dining room.

I had to wait for my preferred brand to ship so I picked this up with next day shipping to help clear up aquariums that were being moved. I was curious how good it might be. Seller descriptions from China are a joke, and this was no exception. The part that really stood out was “quiet brushless motor “, and the exact same motor design as powerhead and most canister filters, hang on filters have been using for over 30 years.
Things I liked: filter stages are easy to load and unload. The filter is mostly made of pretty durable ABS plastic. The hose shutoff valves and release seem to work well. The built in handle pockets make the unit easy to carry for cleaning.
Things I didn’t like: filter stage baskets feel flimsy, I’ll need to be careful. Three of four hose clamp collets were on backward (probably would have still worked fine, just points to QA). Vinyl hose is thin, so crimped from shipping (hot water helps to relax them). The silicone O rings are poorly moulded but seem to be sealing. On/off switch has already failed (broke in the on position, unplugging works fine). Media was a bit random and not placed in the correct order for operation.

Overall it seems decent, but I think still priced high for the quality. I did use a quality silicone lube specifically for seals on all the o rings and other seals and it always helps. If you invest time, money, and yourself into an aquarium I’d say get a known good brand. Need something that does the basics on the cheap this seems adequate.

When I first received this product, it came 2 days late and the UV bulb enclosure was cracked. After speaking to customer service, amazon sent me a replacement, which I received a day early. The hose needed to be rinsed under hot water for 5 minutes, and the bucket took a long while to fill using the internal pump handle used to draw water out from the tank into the hose; I ended up just removing the lid and filling the bucket manually, then using the pump handle to push the water out the rest of the way back into the tank.

After setup was done, I plugged the filter in and found no problems. I switched the UV bulb on and saw it took a couple of seconds to light up (be patient). The electric pump inside the filter is actually pretty quiet & my turtle seems to enjoy the sound of the water falling back in (I used the included attachment with multiple holes for the water to pour out of).

All that’s left to do now is wait and see how long this filter lasts.

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.
