Bromine tablets are a popular choice for maintaining clean and hygienic hot tubs. These tablets are designed to slowly dissolve and release bromine into the water, effectively killing bacteria and other harmful contaminants. Unlike chlorine, bromine is less harsh on the skin and eyes, making it a preferred choice for those with sensitive skin. Additionally, bromine tablets are easy to use and can be added directly to the hot tub without the need for a separate feeder. Overall, bromine tablets are a reliable and effective solution for keeping your hot tub clean and safe for use.
