Highly absorbent chemical filter media pads quickly and efficiently remove impurities, medications, and phosphate from pond water. Simply cut to any size or shape to custom fit any pond 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 absorbent. Used by researchers, hospitals, etc. A great size for wet/dry filters or larger canister filters where the smaller pad is just not enough!
