When the temperature exceeds 20oC these granules can be applied directly to the spa water.  At lower temperatures, or if in doubt, pre-dissolve the granules in clean water in a clean plastic container at a maximum concentration of 10g of granules per litre of water.  Apply the solution to the spa water with the pumps turned on to aid distribution of the sanitizer through the water.

Initial dose : For freshly filled hot tubs, apply chlorine granules to achieve and maintain an initial chlorine concentration of 20ppm for 2 hours. This is called a shock dose and will be sufficient to kill any bacteria present in the tub, filters or pipework. After 2 hours you must ensure that the chlorine level has dropped to less than 5 ppm before anyone enters the water. (The chlorine level may be tested using chlorine test strips dipped into the water).

Daily maintenance : Check the chlorine level daily and re-apply granules as required to maintain a chlorine concentration of 3 - 5 ppm. The amount of product you will need to use is given in the following table.

NB : It is important to maintain a pH level of 7.2 - 7.8 whilst using chlorine to sanitize your spa. Outside of this range the chlorine will not sanitize effectively.
