It’s safe to use your hot tub or spa in as little as 20 minutes after adding the granules to your water. What is oxidisation? Oxidation occurs when chloramines, oils and organic compounds break down in the water. This allows sanitisers (chlorine and bromine) to work efficiently and kill bacteria. What are Chloramines? Chloramines are created from chlorine during the sanitising process. Oxidising (or shocking) breaks down chloramines, making them revert to chlorine, which keeps levels regulated. My water has become cloudy; will it help? Yes, it'll restore the water and make it crystal clear. If you need more information on shock treatments, check out our how to shock your hot tub guide.
