Highly adsorbent chemical filter media pads quickly and efficiently remove impurities, medications, and phosphate from aquarium water. Use in conventional power filters, undergravel filters, and the chemical filtration compartment of canister filters. Simply cut to any size or shape to custom fit any aquarium filter. Rapidly improves water clarity and actively removes harmful organic and various inorganic waste buildup for several months. Changes color to indicate the pollutants being removed and when Poly Filter is exhausted. Will not leach pollutants upon saturation. (See the Test Kit section for phosphate and copper test kits to help monitor levels.) Industrial grade 12" x 12" Poly Filter pad is stronger and more adsorbent. Used by researchers, hospitals, etc. A great size for wet/dry filters or larger canister filters where the smaller pad is just not enough. For freshwater and marine aquariums.
