Description

This super biochemical sponge filter is a filter that keeps your aquarium always clean. The filter provides mechanical and biological filtration for easy aquarium maintenance. As a mechanical filtration,it use 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 is also suitable for Discus breeding tanks,small tropical fish tanks and fry stock tanks.
