Sodium dichloroisocyanurate (NaDCC) - Dichlor is a chlorine compound used to purify drinking water also swimming pool and spa water. Its full name is sodium dichloro-s-triazinetrione or dichloroisocyanuric acid. In chemical language technically can say dichlor is the cyanuric acid molecule with two chlorine atoms and one sodium atom. This combination is a stable chlorine, which comes as a colorless solid. The cyanuric acid extends the life of the chlorine by shielding it from ultraviolet rays.
The requirements for pool water testing in the application of dichlor based products should be indicated on the product label. The primary parameter to be tested is the level of FAC in the water. The choice of testing methods will vary depending on the type of pool (residential or commercial) and local regulations and standards. The product label should recommend that the pool water quality be properly balanced. This requires testing of the pool water balance parameters of pH, alkalinity, calcium hardness, and stabilizer (i.e. cyanuric acid).

The amount of product to be used or dispensed depends upon the specific application and the volume of water being treated. For example, in routine sanitizing use, the objective is to maintain a residual available chlorine (FAC) concentration of 1.0 ppm – 4.0 ppm for pools and 2.0 ppm – 5.0 ppm for spas. The label use instructions will explain how to determine a typical dosage for the water volume to be treated. Label use instructions will similarly define dosage requirements for other product applications such as oxidation, shock treatment or superchlorination.
