What is the role of soda ash in managing swimming pool water?

Soda ash, also known as sodium carbonate, is used in swimming pool water management primarily to raise the pH levels. Maintaining the correct pH balance is crucial for optimal chlorine effectiveness, water clarity, and overall water quality. When the pH level of pool water becomes too low (acidic), it can lead to skin and eye irritation for swimmers and reduce the effectiveness of chlorine as a disinfectant. By adding soda ash, which is an alkaline substance, the pH levels increase, helping to create a more neutral environment that is comfortable for swimmers and enhances the performance of chlorine in keeping the water clean and safe.
