What is the target range for total alkalinity in pool water?

The target range for total alkalinity in pool water is 80 to 120 parts per million (ppm). Total alkalinity serves as a buffer for the pH level in the pool, helping to stabilize it against sudden changes. When alkalinity is within this range, it effectively prevents pH swings, allowing for a more balanced and comfortable swimming environment.

A lower total alkalinity can lead to corrosion of pool equipment and surfaces and can cause pH levels to fluctuate, making it challenging to maintain proper chemical balance. On the other hand, if the total alkalinity is too high, it may lead to cloudy water and difficulty in adjusting the pH level. This balance is crucial for maintaining the overall quality of the pool water, ensuring both safety and comfort for swimmers.
