Why is pH important?

Maintaining a proper pH level can be just as important as having chlorine in the pool at all. The pH level in your pool should be about the same as the pH level of human tears, 7.2. A pH level of 7.2 - 7.6 is optimal.

Chlorine is about 10 times more effective at sanitizing your water when the pH is at 7.2 rather than at a high ph level of say 8.2. pH can best be measured with a "drop" type test kit, versus a "test strip" which can be easily misread. if you find the pH level is high, the best way to lower pH is by using a safe to handle dry acid like Pro Balance pH- . If its too low (ie below 7.2 then add Pro Balance pH+.
