The pH level of your pool water is a vital element of your pool's overall water chemistry. PH measures how acidic or basic the water is on a scale of zero to 14, with the ideal pH for swimming pools falling in the range of 7. 2 to 7. 6. When the pH level of your pool falls below 7. 2, the water becomes acidic and can cause eye irritation, corrosion of metal pool equipment, dissipation of chlorine, etching of plaster walls and unsightly stains.
