DuraChlor pH DownpH Down reduces the pH of water in swimming pools. pH levels should be maintained between 7.2 and 7.6. When the pH levels exceed 7.6, the water can become cloudy and conditions are favorable for scale to form. Additionally, high pH may cause sanitizers to be less effective in the water. Features: Lowers pH in swimming pool water Easy to use formula Safer than HCI or Muriatic Acid Granular formula Size: 50 Pounds Active Ingredients: Sodium Bisulfate 100% Directions for use: The ideal pH of swimming pool water is between 7.2 and 7.6. If a test kit reading indicates that the pH is greater than 7.6, sprinkle 1/2 a cup of DuraChlor pH Reducer directly into the pool for every 10,000 gallons of water. Wait two hours and test again. If the pH reading is still greater than 7.6, repeat application.
