To keep your hot tub or swim spa water clean and germ-free, chlorine tablets are the most popular choice. They are safe, simple, and hygienic, and can be used with a tablet dispenser to ensure slow and safe erosion without damaging the spa shell. Regular use of chlorine tablets helps to kill bacteria and keep the water in pristine condition. After adding the tablets, it is recommended to wait for about 30 minutes before entering the spa to allow the tablets to work. For best results, we recommend using official Jacuzzi® Chlorine Tablets, which require less product to achieve the same level of sanitisation as other chlorine products. To ensure optimal levels of sanitiser, pH, and Total Alkalinity, use alongside Test Strips.
