Warren Clark –
Used this in my nano betta tank and it’s made a big difference in water clarity. The sponge stays clean and the fish seem more active. Great for small tanks with delicate fish.
Evan Carr –
Perfect for quarantine. The filter works quietly and doesn’t stir up the water much. My discus fish have stayed healthy after a few weeks of use.
Alexander Burgess –
Works well as a polishing filter with my canister. The airflow is steady and the sponge maintains its shape even after several weeks of use.

Installed it in a breeding tank and noticed better water quality. The bacteria colonies seem to grow well, and fry are thriving.
