6 Water Balancers Accurate control of the pH of swimming pool water is essential for swimmer comfort, equipment life, chlorine effectiveness, and compliance with health codes. Operation at a pH below 7.2 may cause corrosive damage to pipes and equipment, pool walls, and be uncomfortable for swimmers. High pH reduces the effectiveness of sanitizers, encourages algae growth, and can damage equipment. Most state health departments require that the pH of swimming pool water be kept between 7.2 and 7.8.
