While swimming pool disinfectants are used to keep pool and spa water clean, clear, and free of bacteria, pH and water balance are essential for keeping the water both comfortable to swimmers' eyes and skin as well as balanced to protect the pool shell, plumbing and equipment. If pH levels are not kept within the appropriate range, the resulting unbalanced water can damage the pool shell and make the water uncomfortable to swim in. The major components of water balance are pH, total alkalinity, calcium hardness, and total dissolved solids. Chlorine and pH readings should be taken daily. Total alkalinity, calcium hardness, and total dissolved solids readings can be taken weekly or bimonthly.
