Hang on Aquarium Filter 20-40 Gallon Fish Tank Filter - 4-Layer Filtration System with Double Waterfall, Hang On Back Filter for Efficient and Silent Operation (701)

Within hours of putting it in the tank the foggy water cleared up. It's been about a month and still working great. It's kinda big, we have it in a 40 gallon tank. All you hear is the water. Great for the price. Haven't changed the filters yet, haven't needed to but the filters seem pricey.

This is a really nice filter pump for the price, easy to assemble and comes with media

The filter worked good for the first two weeks it wasn’t that strong but it was better than nothing and then it just completely gave out and barely started dripping out water it was loud from the beginning and gave me a headache y’all should just go to Walmart instead

Great water filter system, super easy to install. It filters well. It is a little noisy and I can’t seem to get the flow to adjust properly to try and help make it not so “drippy” sounding. It’s perfect size for my 32 gallon tank and works great compared to my old sponge filter set up.

Great quality product

The seal was not sealing the first time. Luckily I returned it and the seller sent me a new one free of charge for the defective one. Great customer service and the second one works great. I think I just got bad luck with the first one but the seller made it right! However it's not the best quality. Filter is now making a gurgling noise so is air getting in somewhere...

Romeo (turtle) dirty up the tank by morning it's all clear. Romeo and I are happy with this item.

My filter stopped working literally the day this new one arrived and the best part is that tgis filter is heavy duty and really has my fish/snail tank looking really clean.
