What is the recommended range for total alkalinity in swimming pools?

The recommended range for total alkalinity in swimming pools is 80 to 120 ppm. Maintaining total alkalinity within this range is crucial for several reasons. First, total alkalinity acts as a buffer for pH levels, helping to stabilize and prevent rapid fluctuations that can lead to water quality issues. When alkalinity is within this recommended range, it helps to protect the pool surfaces and equipment from corrosion and scaling.

Additionally, adequate total alkalinity enhances swim comfort by preventing irritation to eyes and skin, which can occur if the pH level becomes too acidic or alkaline. This range also supports the overall effectiveness of chlorine and other disinfectants in the water, ensuring a safer swimming environment.

Maintaining alkalinity outside this recommended range may lead to challenges in properly balancing pH levels, making it more difficult to manage water chemistry correctly.
