IMPACT OF TOTAL DISSOLVED SOLIDS ON SWIMMING POOL WATER

After a pool has been in use for some time, dissolved solids may begin to accumulate. These solids which cannot be filtered include body wastes and oils, suntan lotion, stabilizer, chlorines, algaecide, dirt, pollen, and other environmental components. Indoor pools and outdoor pools have similar problems with solid waste buildup requiring draining or partially draining the pool and refilling with fresh water. Most pools should be drained after 3 to 5 years.

The ideal range for Total Dissolved Solids (TDS) in your pool water is 1,000 to 2,000 (ppm), with a minimum acceptable reading of 300 and a maximum of 3,000. Having TDS at a proper level in your pool water will help maintain water balance. The level of total dissolved solids can only be altered by draining and refilling the pool with fresh water.
