Think of your pool liner as your pool’s skin – Treat it properly and it looks great. Fail to take care of it and it will deteriorate, stain and not hold up.
So let’s take a bigger look at the picture. What is pH? Well, the pH is simply a measure of the acidity in water. Levels of pH range from 0-14 with 0-7 being acidic and 7-14 being basic. But what does this determination mean for swimming pools? It’s rather simple. The balance of pH is important because it allows chlorine work properly by disinfecting water, pH balance also makes it safe for your pool’s filtration system and pool equipment. Having a low pH or a pool that’s too acidic can cause damage to those systems and equipment and as well as the pool liner. Outside of material problems, having a low pH can also cause irritation of the eyes and skin.
Not balancing the pH, total alkalinity and calcium hardness are three big no-nos, not only for your vinyl pool liner but for your pump and filter as well. When the pool is in heavy use, pH levels should be checked daily (and the same goes for chlorine levels as well). To lower pH, you use the chemical sodium bisulphate and to raise the pH, you would use sodium carbonate
If you see cloudy water and scaling, your pH is too high. If your pH is too low, you risk damage to the liner. Keep the total alkalinity for your swimming pool should between 125-150 ppm (parts per million) for vinyl-lined pool. Adding a pH decreaser will bring down alkalinity and as well as the pH. You want to maintain a pH level of between 7.4 and 7.6 Acidic water will wear out your vinyl pool liner. Bear in mind that heavy rain can raise the acidity of the water.
After adding any chemicals to your pool, please wait a few hours and let these additives work. Then take more measurements.
To recap, you should always keep a close eye on your pool liner for any staining, wrinkling or grime. First adjust the total alkalinity, then the pH. The right pH level lets the chlorine in your pool do its job on bacteria.
