Pool Mate 4-Pounds Premium Pool Stabilizer and Conditioner, Concentrated Cyanuric Acid for Pools, Helps Chlorine Last Longer

This product disperses rapidly to establish a chlorine protection quickly. It stabilizes pool water and extends the life of the disinfectant. Use a reliable test kit to determine the stabilizer concentration in the pool water. Follow the included chart to bring the pool water to the desired range of 40-100 ppm. If the pool is new, just refilled, or has no stabilizer; add 4 oz. of this product per 1000 gallons to give the desired range of 40-100 ppm. 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 2.0-4.0 ppm and pH at 7.4-7.6.
