Our chlorine granules are completely soluble and are used to stabilise your hot tub’s pH levels. They contain a stabilising agent to protect your hot tub against the effectiveness of chlorine in the water when exposed to sunlight, making the granules ideal for daily chlorination. Guidance; How much chlorine to add: A heaped teaspoon holds approximately 8g of chlorine granules. As a general guide, to increase a 1500L hot tub from 0ppm to 5ppm you will need to add at least 12g of Chlorine Granules. So approximately one and half teaspoons should be enough. How to add to your hot tub: Add your chlorine granules in stages (8-12g) into 10 litres of freshwater using a clean plastic container and mix carefully. Slowly pour the mixed solution into your hot tub water near to the return inlets, then thoroughly rinse out the container. Dosage: Heavily used hot tubs, maintained at high temperatures, may require more frequent dosing with Chlorine. Individual requirements may vary, test using a poolside test kit and adjust the dose rate as necessary to maintain a chlorine level of 1-3 ppm or mg/litre. pH Control: To keep your hot tub at the optimum pH level, the water should be maintained at a pH level of around 7.4 and between 7.2 and 7.8 at all times. If the hot tub is too alkaline (8.0+) the efficiency of the chlorine is around 20%. If the pH level is too hight you could damage your hot tub and swimsuit, it is vital to check the pH level of you hot tub before use using a simple pH testing strip.
