BIOLOGICAL SPONGE FILTER (SMALL)

Look how clean that tank is!

Everyone liks sponge baths. Including your fish. So give htem this sponge filter and clean up their water AND fins. This mini bio filter sits in the corner of your tank and basically works through air lift. You plug in an air pump (not included) and it’ll force air through the system and water will be magnetized to go through it as well too. The water gets cleansed by beneficial bacteria in the sponge and then you get crystal clear water by the power of air. It’s magic.
