What is the minimum total alkalinity required for pool chemistry?

The minimum total alkalinity level recommended for pool chemistry is 80 mg/L. Total alkalinity serves as a buffer for pH levels in the pool water, helping to stabilize the pH and prevent rapid fluctuations. Maintaining total alkalinity at or above this level ensures that the water remains balanced, which is essential for effective sanitation, swimmer comfort, and the protection of pool surfaces and equipment.

When the total alkalinity falls below 80 mg/L, it can lead to issues such as pH instability, which can cause damage to pool surfaces and affect the effectiveness of disinfectants. This level serves as a standard benchmark, ensuring that the water is prepared to cope with external factors and swimmer activity without significant variations in chemical balance.
