What is the ideal total alkalinity level in pool water?

The ideal total alkalinity level in pool water is around 100 ppm (parts per million). This level is crucial because total alkalinity acts as a buffer for the pH levels in the water, helping to maintain a stable and balanced environment. When total alkalinity is within this range, it helps prevent rapid fluctuations in pH, which can lead to issues such as skin irritation, equipment corrosion, or decreased effectiveness of chlorine.

Maintaining total alkalinity at approximately 100 ppm also supports optimal water clarity and comfort for swimmers. It ensures that the water chemistry remains stable, which is essential for proper disinfection and overall pool maintenance. Levels that are significantly lower or higher can lead to problems, thus reinforcing the importance of keeping total alkalinity at this ideal level.
