What is soda ash used for in pool water?

Soda ash, chemically known as sodium carbonate, is commonly used in pool maintenance to raise the pH levels of the water. When pool water becomes acidic, it can lead to various issues such as corrosion of equipment, discomfort for swimmers, and reduced effectiveness of sanitizers. By adding soda ash, the carbonate ions react with hydrogen ions in the water, effectively increasing the pH and bringing it back to the desired range of 7.4 to 7.6.

Maintaining proper pH levels is crucial for the overall health of the pool environment—ensuring that chlorine operates efficiently and preventing potential damage to the pool's infrastructure. This elevated pH level contributes to a more balanced and safe swimming environment.
