pH Reducer is used for lowering the pH in your swimming pool water. Haviland pH Reducer is a granular product that is a safer product to store and use than muriatic acid. High pH will cause sanitizers such as chlorine to lose its effectiveness and can cause eye and skin irritations.
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 Haviland 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.
