Pool Water pH Level Increase/Decrease

Adjusting pool water pH is crucial for safety and comfort. To lower pH, add acids such as muriatic acid or sodium bisulfate. To raise pH, use alkaline substances like soda ash. Regular testing with strips or liquid kits helps maintain a balanced pH within the ideal range of 7.2-7.8. This balance prevents eye irritation and corrosion, ensuring clean and clear water for an enjoyable swimming experience. Proper pH management also extends the life of pool equipment and surfaces. Keeping the pH in check is essential for maintaining the overall health and longevity of your pool.
