What is the recommended range for maintaining alkalinity in swimming pool water?

Maintaining the alkalinity of swimming pool water within a range of 80 to 140 parts per million (ppm) is crucial for several reasons. Alkalinity acts as a buffer for pH fluctuations, helping to stabilize the water chemistry. When alkalinity is within this range, it ensures that pH levels stay balanced, which is essential for swimmer comfort and effective disinfection. Proper alkalinity levels also help prevent corrosion of pool equipment and surfaces, as well as scaling, which can occur if alkalinity is too high. Furthermore, the recommended range supports optimal control of other chemicals in the pool, enhancing overall water quality and minimizing water treatment issues.

Choosing a range significantly outside this recommended zone could lead to various pool maintenance problems, such as difficulty in controlling the pH level or increased chemical costs. Therefore, the 80 to 140 ppm range is recognized by pool maintenance professionals as the ideal standard for achieving balanced water conditions.
