What is total alkalinity (ta)?

Total alkalinity is a measure of the alkaline substances in the water of your pool. Total alkalinity is important, as it determines how resistant your pool is to large changes in pH, known as pH bounce. Alkaline substances act as buffers against such pH changes, which will disrupt your pool. For a stable pool, the ideal range of total alkalinity is 80 to 150 parts per million (ppm).
