pH Level - pH is a measure of how ‘acidic’ the water is in the pool. The pH scale runs from 0 to 14 and measure the acidity/alkalinity of the water. A pH value of 7 is neutral, a pH value below 7 is acidic and a pH value above 7 is alkaline. Water in the acidic range becomes increasingly corrosive as …
