Elevated pH in swimming pools is a common water chemistry imbalance. This condition occurs when the water’s hydrogen ion concentration is too low, resulting in a reading above the ideal range of 7.2 to 7.8. Several factors contribute to this issue, including the addition of certain chemicals, particularly those designed to raise alkalinity, as well as the presence of dissolved minerals from source water or fill water. Additionally, improperly balanced pool water can exacerbate the problem.
Maintaining appropriate pH levels is crucial for swimmer comfort and the longevity of pool equipment. Water with a high pH can lead to scale formation, cloudy water, and reduced sanitizer effectiveness, rendering chlorine less efficient in its role of disinfecting the water. Moreover, this imbalance can cause irritation to swimmers’ skin and eyes, undermining the enjoyment of the pool. Addressing high pH not only ensures a more pleasant swimming experience, but also prevents costly repairs or replacements of pool infrastructure.
