Directions for Use:

  • Clean or backwash your filter before adding PoolRx and remove all debris from skimmer and pump basket.
  • Place the PoolRx pool unit into Pump Basket or Skimmer. 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.
