Juwel BioPad Poly Pads remove coarse particles of dirt in the water, thereby serving as a mechanical pre-filter. As a mechanical pre-filter, it protects the Juwel aquarium filter from rapid soiling and means that you don't have to clean the other filter media as often. Juwel filter floss consists of fine, residue-free polyester material and is suitable for use in both saltwater and freshwater aquariums.
