PH is the measurement of acidity of water – measured on a scale of 0 to 14 with 7 being neutral. Not only do proper pH levels allow the other chemicals to do their work, but it is important to note that low and high levels can cause damage to a vinyl liner.
- Low pH Levels: A pH below 7.0 means the water is very acidic. Under the right circumstances with pH below 7.0, the liner can actually grow and develop unsightly wrinkles.
- High pH Levels: As the pH approaches 8.0, the water becomes very basic (alkaline). High pH greatly accelerates the aging process and shortens the life of the liner. Chlorine is also much less effective at higher pH levels. At a pH of 8.0; chlorine is only 22% effective.
Improper pH levels can lead to the vinyl liber absorbing water, causing it to expand. This can create wrinkles. It’s the same concept as spending too much time in the bathtub and your fingers become pruned and wrinkled!
