Routine Chlorination: For best results, maintain pH in the range of 7.2 to 7.6. Maintain total alkalinity in the range of 60 to 120 parts per million (ppm). Maintain calcium hardness above 200 ppm. Check available chlorine with a suitable test kit. Each 0.2-0.4 ounces of this product will provide approximately 1-4 ppm available chlorine in 500 gallons of water.
For Unstabilized Pools: Add 5-7 ounces of this product per 10,000 gallons of pool water daily or as often as needed to maintain the free available chlorine residual at 1-4 ppm.
For Pools Stabilized Using Stabilizer and Conditioner: Add 3-5 ounces per 10,000 gallons every other day or as often as needed to maintain the free available chlorine residual at 1-4 ppm.
