2. Test your waters pH, alkalinity, and calcium hardness and adjust to the correct level.  Adjust pH to 7.2-7.6, adjust alkalinity to 80-125 ppm for plaster pools and 125-150 ppm for vinyl or fiberglass pools, adjust calcium hardness to 200-275 ppm for plaster pools and 175-225 for vinyl or fiberglass pools.  Be sure to follow label directions when using other products as outline in directions for this product

3. Check the free available chlorine level and adjust to 1-3 ppm by adding a granular chlorinating product.
