In The Swim pH Reducer - Muriatic Acid Alternative for Pools, Spas, and Hot Tubs - Prevents Cloudy Water - 50 Pounds

In The Swim Granular pH Reducer is safer and easier to store than liquid muriatic acid. Use pH reducer whenever your pH level rises above 7.6. The ideal range for your pool's pH should be 7.2-7.6. High pH levels can cause things such as cloudy water, skin irritation, and damage to your pool and equipment, so it's a good idea to have pH reducer on hand for those times when your pH level is high. 10lbs. of granular pH reducer is equivalent to 1 gallon of muriatic acid. Initial Dosage: 15-30 oz. per 10,000 gallons. Granular Sodium Bisulfate.
