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.
