180GPH Hand on Filter for Aquariums，20-40 Gallon，Silent Multi-Stage Filtration for Fish Tank，Or Ultra-Low Water Level Turtle Tank，Increase Water Flow and Oxygen Power Filter

Working VERY well in my heavily populated shrimp/snail tank. The 4 stage filtration I am able to do in this wonderful product makes the water crystal clear and keeps my shrimp and snails healthy with steady water parameters. The thoughtful addition of a sponge cover for the inlet is an amazing bonus to keep lil shrimplets out of the filter. Great job!

It's a decent filter; however, there are no replacement parts for it... and the manual says you have to replace the cotton every 4 weeks. When I asked the seller, they said they'd be available "as soon as possible". Ridiculous. No i have to replace the whole thing with another brand. Don't waste money on this unsupported unit.

The aquarium filter runs quietly with a steady water flow that doesn’t disturb the fish. The filtration works well, keeping the water clear and reducing the need for frequent changes.

This filter is the worst filter that I ever bought in my life. Do not buy this filter. I’m trying to get a refund on my money back and nobody’s even responding.

The filter has a quiet but very strong pump. It can be easily hang on the edge of the aquarium. The water flow is strong, and I can choose different flow direction and pattern. No leakage at all. Really like it.

Liked the product at first, it's low profile hang in the tank, all the adjustable features, it's kept the tank water moving and filtered, almost seven months in it simply lost flow, after inspection there should be no reason for this and now you plug it in and it runs full power for any where form 10 minutes to a couple hrs, unplugging it for a day it will temporarily work again, maby it's just mine? Would like to try another one if I could trust I would get more than seven months of use!

Pros:* Very Quiet* Effective at keeping a 20L clean* Extremely adjustable water flow.* HOB / Canister cross.* Can use your own filter media with the baskets.Cons* Replacement filter media not always available (Can be solved by cutting your own)* Power cable could be a little longer* Baskets are a little hard to separateReview:I have had mine on a 20L tank for almost 2 years now. its been a great Canister/HOB crossover that I think is a great concept. It is a tad bit frustrating that the replacement filters aren't in constant supply though and that they seem to come up for sale every once in a while forcing you to have to check back on the main listing a couple time a month. There is a solution for this though. For anyone who has one and can't buy replacement filters. If you save the blue bio foam that comes on the bottom of the filter stack then you can use it as a templet to cut out new filter media for it. You can get filter media either here on Amazon or at a local pet store. I personally cut floss pads and bio foam for mine and then put a small bag of activated carbon in the top basket where the carbon pads usually go. It keeps my tank very clean and the fish.

Easy to install! I've been using it for a week and I feel the water quality has improved a bit. The fish are healthy, which is great.
