What do total dissolved solids indicate in swimming pool water?

Total dissolved solids (TDS) refer to the cumulative concentration of all dissolved substances in the water, which include organic materials, minerals, salts, and metals. By measuring TDS, pool operators can gain insights into the overall chemical balance and purity of the water. High TDS levels can affect water clarity, sanitization efficacy, and comfort for bathers, as it may indicate an accumulation of contaminants. Therefore, understanding TDS is essential for maintaining optimal swimming pool water quality and ensuring a safe and pleasant environment for users.
