What is the acceptable level of total alkalinity in swimming pool water?

The acceptable level of total alkalinity in swimming pool water is 80 to 120 ppm (parts per million). Total alkalinity acts as a buffer for the water's pH, helping to stabilize it and prevent large fluctuations that can adversely affect the pool's water chemistry and overall clarity.

When alkalinity levels are within this range, they help maintain balanced water chemistry, which is critical for the health of swim pool users, the effectiveness of sanitizers, and the longevity of pool surfaces and equipment. Maintaining proper alkalinity levels can also reduce the risk of corrosion or scaling in the pool system.

If the total alkalinity falls outside this range, it can lead to challenges such as difficulty in maintaining pH levels, which can create an uncomfortable swimming environment or even lead to chemical imbalances. Therefore, the range of 80 to 120 ppm is recognized as the optimal range for effective pool maintenance and user safety.
