xy-2837 large sponge filter
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 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.
