pH- Potential of Hydrogen

Chlorine Effectiveness Scale as Depending on pH (Potential Hydrogen)

• The pH is a measure of hydrogen ion (H+) concentration in water.
• A person’s body has a pH between 7.2 and 7.8.
• Total Alkalinity or TA acts as a buffer to stabilize the pH.
• The pH is lowered by adding muriatic acid (MA).
• Sodium carbonate also called soda ash or washing soda raises pH.
• If pH is below 7.2 or above 7.8 there will be a reduction in swimming comfort.
• If the pH is too low then anything metal will corrode staining your pool plaster.
• If the pH is too high there will be scale formation, discoloration of pool walls and chlorine becomes inactive causing sanitation problems.
