Visually clear and clean water would normally indicate water quality, however, it is only by testing the water balance, residual sanitiser and other support chemicals, that the assumption of quality can be confirmed.
Simple kits are available to carry out basic water testing, particularly for chlorine and pH.
Free chlorine must be available in sufficient quantity at all times to take care of the changing demands placed upon it, and pH must be maintained within the 7.2 and 7.6 range to ensure chlorine effectiveness. Regular pH control also contributes to water clarity and comfort of bathers.
Pool owners should carry out these two simple tests, at least once per week, and adjust levels accordingly.
Thereafter, monthly testing by a pool service professional of alkalinity, hardness, stabiliser, salt, total dissolved solids, or any other factors relevant to the water treatment programe is recommended.
