What is pH? A pH reading of a swimming pool refers to the balance of acid and alkaline substances present in the water. It is measures on a scale of 1-14, with ideal pH levels of 7.2-7.6 for swimming.   Why do I need to maintain pH? Maintaining pH levels protects your pool and equipment but also you and your family. If you have a low pH level, the water becomes acidic. With readings at this end of the pH scale, the water can corrode metals in equipment, and your pools surface can be affected by etching or erosion of tile grout. Low pH can also cause burning of your nose and red eyes and also dryness of your skin and scalp. If you have a high pH reading, this means the water is highly alkaline. High pH levels can make the water appear cloudy, and you may notice some scaling on the surface of the pool. You may also see a reduction in the effectiveness of chlorine, so your pool could go green very quickly. As it is with low pH, you can also experience burning of your nose and red eyes as well as dryness of your skin and scalp.   How do I maintain pH? You may feel like you’re constantly adding acid to your pool to bring your pH levels down. This is because as chlorine is added, it has a direct effect on pH, causing it to increase. As chlorine is (or should be) added to your pool daily, each dose will increase your pH readings depending on the amount added. The easiest way to maintain your pH levels is to install a pH probe, this adjusts your acid input automatically with little to no intervention.
