Description
This sponge filter uses a simple airlift system - just add an air pump and airline - to combine gentle mechanical filtration with biological filtration in one unit. Water is drawn through the foam sponge, trapping debris while beneficial bacteria colonise its surface and break down fish waste into safer compounds, keeping ammonia and nitrite levels in check.
- Airlift design runs quietly with no motor of its own
- Foam media supports beneficial bacteria for biological filtration
- Gentle water flow makes it safe for fry and shrimp
- Well suited to breeding and grow-out tanks
Because its intake is too gentle to pull in small fish or shrimp, it is a popular choice for breeders who need reliable filtration without risking their youngest or smallest tank residents. Requires a separate air pump to operate.
