I bought this small filterpump for my 2 gallon aquarium. Pros: my Betta (Gil) glow fish (Finnegan)and lastly my snail (Turbo) seem much more active. Pro: no more scummy film on top of water. Con: for a small device it's very loud. Con: directions on package are very unclear.

Awesome little unit

Works great! You might need a different pump, but this filter works wonderfully. Have used one of these off and on for many years.

Don’t waste your money

Does not do what it is suppose to do. I have a small glass that I have a beta in and it just cannot do what’s needed to keep clean
