The pH scale measures how acidic or basic a water-based solution is. Lower pH values indicate that a solution is acidic and higher pH values mean that a solution is basic. This is important for your pool, in ensuring the balance between acidity and alkalinity. If your pH is less than 6, this implies your pool is too acidic, while a pH of more than 8 means your pool is very alkaline. The perfect balance for a pool is a pH between 7.2 and 7.6.
