This is a friendly reminder from McEwen Industries to take care of your vinyl pool liner throughout the summer.
Always maintain a proper water balance. pH should fall in the 7.2 – 7.6 range, total alkalinity should be at 100-150 ppm, and calcium hardness should be a 200 ppm minimum.
Avoid allowing your pH to drop below 7.0. This can cause your liner to form wrinkles.
Remember to maintain free chlorine residual between 1.0 and 1.5 ppm. If free chlorine drifts below 1.0 ppm, algae and bacterial growth can hold more easily and may cause staining of the vinyl liner. Chlorine is quickly absorbed by sunlight. For this reason, it is recommended that all vinyl swimming pools be stabilized with cyanuric acid and that a range of 25-100 ppm be maintained.
Have a safe and happy summer!
