Dry granular product for raising the pH of water.
The ideal pH of swimming pool water is 7.4 to 7.6. If a test kit reading indicates that the pH is less than 7.4, sprinkle one pound (2 cups) of this product directly into the pool for every 10,000 gallons of water. Wait two hours and test again. If pH reading is below 7.4, repeat application. If pH reading is above 7.6, add a pH reducer as per directions on label. It is best to have total alkalinity in range before adjusting pH, as you will get more lasting results.
