What is the acceptable range for total alkalinity in a standard commercial pool?

In commercial pools, maintaining proper water chemistry is crucial for the health and safety of swimmers as well as the integrity of the pool equipment. Total alkalinity acts as a buffer for pH levels, helping to stabilize the pH and prevent large fluctuations that could harm bathers or equipment.

The acceptable range of 80-120 ppm for total alkalinity is based on the need to provide a sufficient buffer against rapid pH changes, which can be influenced by various factors including the number of swimmers, organic material, and chemical additions. When total alkalinity is maintained within this range, it minimizes the risk of pH swings, helping to protect both the pool equipment and the comfort of the swimmers.

Additionally, achieving this range allows for easier management of the pool's water chemistry. If total alkalinity is too low, pH levels can be unstable and may experience sharp changes. Conversely, if total alkalinity is too high, it can lead to cloudiness in the water and may require more chemicals and effort to bring levels back into a desirable range.

This range ensures effective water clarity, comfort for swimmers, and reduced strain on chemical balance, which is vital for commercial pool management.
