Aquaclear Filter Insert Clear Foam

Insert is a mechanical filter media that effectively removes particles and debris from aquarium water. It also prevents particulate waste from prematurely clogging other media in the filter. Primarily a mechanical filtration media, it also provides powerful biological filtration as friendly bacteria eventually grow inside its pore structure. Exclusively designed for the AquaClear 5 Power Filter, the Foam Filter is safe for fresh and saltwater aquariums. Single pack.
