Chlorine Tablets


Chlorine tablets, a sanitizing agent, are employed to eradicate bacteria and other deleterious microorganisms within aquatic environments such as swimming pools, hot tubs, and other water bodies. These tablets are predominantly composed of sodium dichloroisocyanurate (SDIC), a white, crystalline compound that undergoes dissolution in water to release chlorine.

The market offers these chlorine tablets in an assortment of dimensions and potencies, facilitating their application in both manual and automated chlorination systems. For the employment of chlorine tablets within a manual chlorinator, one should adhere to the specified guidelines provided by the manufacturer, placing the tablets directly into the chlorinator. Conversely, in the context of an automated chlorinator, the tablets should be positioned within the feeder basket of the chlorinator, thereby enabling the device to autonomously dispense the necessary quantity of tablets into the aquatic environment, as per requirement.
