Add this product slowly into the skimmer, or if desired, premix in a pail of warm water and then add directly to the skimmer. Be sure the filter is clean. Recirculate the water continuously for 24 hours to dissolve completely. Always maintain the chlorine residual in your pool at 2.-4. ppm and pH at 7.4-7.6.
