The pH level of your pool affects every other chemical balance in pool water. pH is a measure of the level of hydrogen ions or acidity of the pool water. Measured on a logarithmic scale, a pH of 0 indicates extremely acidic conditions, and a pH of 14 indicates extremely basic conditions. A pH of 7 is neutral.
