What Should Pool pH Be? Maintaining Proper Pool Water Balance

pH is the measure of the acidity/basicity of the pool water.

Maintaining a pH between 7.2 – 7.6 will:

  1. Ensure comfortable swim conditions
  2. Discourage liner wrinkling and discoloration
  3. Allow chlorine within the recommended range of 1.0 to 3.0 ppm to keep the water and liner free of algae, bacteria, and mold

Adjust pH after confirming alkalinity and calcium hardness. Maintaining the correct pool pH level protects swimmers, pool equipment, and vinyl pool liners.
