Recommended flow rate is 2 gpm and maximum pressure is 100 psi. Do not allow the filter to freeze. Back flush filter monthly to preserve ideal flow rate. Once the filter has been used, run water through the filter at least twice monthly, or store in a refrigerator to prevent media oxidation.
Please note that because the media could contribute small amounts of zinc ions to the pond water over several years, these systems are NOT recommended for use in filling fish ponds, especially in the care of Koi fish.
