Why it's a great deal
Increase the total alkalinity of your swimming pool or hot tub water and prevent it from becoming corrosive
Help control your water's alkalinity level, reduce the acidity level and maintain a correct PH
Water that's too acidic can cause chlorine treatment not too work effectively leading to pool/hot tub damage and irritation
Recommend using the alkalinity increaser if your water drops below 7.2 on the pH scale or below 80mg/L alkalinity level
Clearwater is a BISHTA approved member and recommended by brands such as Bestway and Lay-Z-Spa for reliable, safe and high-quality water treatment
