Water Chemistry Problems: TDS

PROBLEM:  High total dissolved solids (TDS) (above 2500 ppm or 1500 above source)

POSSIBLE CAUSES:  Use of water that is naturally high in dissolved salts, long term use of pool without replacing any water or long term buildup due to chemical additions — every chemical added to pool water contributes to TDS

SOLUTION:  Replace some of the water with fresh water that is low in TDS. If there are no signs of a clarity problem, TDS is usually not a problem. Replacement of water lost due to pump out, backwashing and splash out will help keep the TDS in check. If there is a persistent water quality problem that defies explanation, TDS should be looked into as a possible contributing factor by bringing a water sample to your professional SUN® dealer.
