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.
