Bio Clear Double Sponge Filter
Bio ClearDouble Sponge Filter
Provides two vital filtrations simultaneously in order to keep a clean and healthy aquarium environment.
The colonization of beneficial bacteria in the many pores of the sponge biologically breaking down harmful substances to harmless substances, thereby keeping healthy aquarium environment.
The suction created through the air driven filter system traps aquarium visible debris into the pores of the sponge, thereby keeping the aquarium water crystal clear.
