Jonathan Poole –
I used this filter in my 10-gallon tank with betta and cherry shrimp. The water clarity improved within a week. It’s easy to install and the sponge stays clean without needing frequent replacement. Great for small tanks.
Bernadette Morgan –
Works well with my discus tank. The biological media supports good water quality. I only need to clean it every few weeks. It fits nicely in the corner of the tank and doesn’t take up much space.

Perfect for baby fish and shrimp. The filter maintains stable water conditions and the bacteria colonies grow well. I didn’t have to change the filter media after a month. Very reliable.
