TDS

TDS, Total Dissolved Solids, is a measure of the quantity of dissolved material in the pool water. In mains water, this comprises of hardness and other natural salts. The level of TDS depends on the source water.

Dissolved Solids in the pool are affected by many factors, including hardness salts, impurities from wind and rain, bather loads and pool treatment chemicals. Levels will gradually increase over time due to evaporation and concentration, so it is important to measure the TDS at regular intervals.
