The maintenance of proper water balance is the most important factor to maximizing the life and appearance of the liner. Proper pH levels allow the chemicals to perform their function. Chlorine needs a certain pH level to kill bacteria and algae. Proper technique is important for water testing. See your Pool Professional for test kits and testing procedures. Be sure to read and follow the written instructions from the chemical manufacturer.
|Factor||Range||In-season Test Frequency||Function|
|pH||7.2 – 7.6||Daily||Allows other chemicals to operate properly|
|Free chlorine residual||1.0 – 1.5/PPM*||Daily||Kills Bacteria|
|Total alkalinity||60 – 125/PPM*||Weekly||Ability of pool to counteract change in pH levels|
|Cyanuric acid||30 – 75/PPM*||Monthly||Stabilizes water chemistry|
|Calcium hardness||175 – 250/PPM*||Monthly||To avoid corrosive conditions in pool systems|
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 the liner. Under the right circumstances with pH at or below 7.0, the liner can actually grow and develop unsightly wrinkles. High pH greatly accelerates the aging process and shortens the life of the liner.
