• If the pH of your pool is always too high, it’s probably because you are using chlorine with a high pH level (granulated chlorine). Adjust the pH by adding pH- to keep the pH level between 7.2 and 7.8.
  • If the pH of your pool is always too low, it’s probably because you are using chlorine with a low pH level (stabilized chlorinating pucks). Adjust the pH by adding pH+ to keep the pH level between 7.2 and 7.8.
  • If the pH fluctuates up or down and it is difficult to keep it between 7.2 and 7.8, make sure you check the alkalinity level of the pool water and keep it between 80 and 120 ppm.
