Use the output of most powerheads, canister filters, submersible filters, and water pumps to spin this unique aerobic aquarium filter. Uses no electricity. Simply attach the adapter to the output tube and the flowing water does the rest. The rotating water deflector spins the aerobic sponge filter 360 degrees so that it is in constant circulation with the water and air.

Aerobic bacteria in the sponge reduce the ammonia, nitrites, and surface deposits in the tank. Promotes better oxygenation while creating a wave effect for moving plants or anemones. Includes an assortment of adapters to fit the output tube of most pumps and filters.
