This super biochemical sponge filter is a simple filter that keeps your aquarium clean.
The filter provides mechanical and biological filtration for easy aquarium maintenance.
*As a mechanical filtration, it uses the air-driven system to create suction that allows the sponge to capture floating particles in the water and return filtered water to the tank.
* As a biological filtration, harmful wastes are biologically transformed into a relatively harmless substance by aerobic bacteria that accumulates in the sponge.
This kind of sponge filter is suitable for all aquariums.
