Ideally place in pump basket for increasedwater flow.- The PoolRx+ pool unit should be added to the pool when the pump has at least 3 to 4 hours left on runcycle. This will ensure the granular completely dissolves out of the unit and through the filter into the pool.- Pump should run during the heat of the day.- Your pool should turn over its total volume of water at least 1.5 times per day. Generally, this will require 6 to 8 hours of pump runtime depending on gallons of water and pump flow rate. Do not re-clean or backwash filter for at least 2 weeks after PoolRx+ pool unit is installed so granular can dissolve through the filter, whether it is a cartridge, D.E. or sand filter.
