Understanding pH Balance

pH stands for “potential of hydrogen” and measures how acidic or basic your water is based on the amount of hydrogen ions (H+) present.

The pH scale ranges from:

  • 0 = most acidic
  • 7 = neutral
  • 14 = most basic (alkaline)

This scale is logarithmic, meaning each number changes acidity by a factor of 10. For example, water with a pH of 6.0 is 10 times more acidic than water with a pH of 7.0.

Ideal Spa pH Range:

7.4 – 7.6

Maintaining proper pH levels is important because:

Low pH (Below 7.0)

  • Can damage spa equipment and plumbing
  • May cause skin and eye irritation
  • Can corrode spa components over time

High pH (Above 7.8)

  • Often causes cloudy water
  • Leads to scale buildup
  • Reduces sanitizer effectiveness

Balanced pH helps maintain crystal-clear water while protecting both bathers and your spa investment.
