The pH level is one of three indicators that will help determine water balance (or imbalance). The pH level is likely the most important indicator of water balance (or imbalance).

While pH is directly related to Alkalinity, the two water balancers are not the same.

If shocking the pool (primarily when to shock the pool) is the most confusing topic for pool owners, then water balance - primarily the relationship of pH and Alkalinity, but really, water balance in general - is almost equally confusing.

You must understand the pH of the water to understand water balance.
