Test kits are used to make basic measurements of free chlorine and pH from a sample of pool water, which are the most important items to control in a swimming pool. Besides chlorine and pH, which should be checked frequently, more sophisticated kits provide tests for acid demand and base demand, total alkalinity (TA), calcium hardness, and cyanurate ("stabilizer") concentration. These additional tests tend to vary only over weeks or months in a well-maintained pool, and thus need not be checked as frequently as chlorine and pH. |
