Why does it matter if my pool’s pH is too high?
Your pool’s pH should be between 7.2 and 7.6. If your pool’s pH gets too high, it will affect the effectiveness of the other chemicals, particularly chlorine. Ineffective chlorine can increase the likelihood of waterborne illnesses, skin irritation, cloudy water, equipment damage, pool tile scaling, and clogged filters. Learn more.
