Bio Sponge Aquarium Filter
Keep your aquarium clean, healthy, and crystal clear with this Bio Sponge Aquarium Filter. Designed to provide both mechanical and biological filtration, this air-powered filter removes floating debris while creating an ideal environment for beneficial bacteria to naturally break down harmful ammonia and nitrites.
The gentle filtration makes it one of the best filter choices for shrimp tanks, betta aquariums, nano fish, breeding tanks, fry grow-out tanks, and quarantine aquariums. Unlike traditional power filters, sponge filters provide excellent water quality without creating strong currents or risking injury to delicate livestock.
Simply connect the filter to an air pump (sold separately) to improve oxygen circulation while maintaining exceptional water quality.
