Are you looking for an alternative way to keep your hot tub clean and sanitized without having to use harsh chemicals like chlorine and bromine? While it isn't safe to go completely chemical-free, there are plenty of non-chlorine and non-bromine alternatives that are gentler on your skin and don't have the strong smell of a chlorine spa. Biguanide is another hot tub sanitizer option that effectively kills bacteria while also keeping the water soft. Biguanide doesn’t degrade with sunlight, temperature, or affect the pH balance of your spa water like traditional chlorine sanitizers can.
