Buy Bromine

Bromine is a popular chemical to use as a spa sanitizer and is often used instead of chlorine.

Bromine has some distinct differences from chlorine and works better in hot tubs, with hotter water and low water volume, than chlorine does. However, bromine is sensitive to sunlight, deteriorating rapidly when exposed to the sun, which is why it is seldom used to sanitize swimming pools. Bromine is usually slightly more expensive than chlorine.

Total Bromine: Like chlorine, there are two forms of bromine, free bromine and combined bromine (or bromamines). Together these two forms are called total bromine. Importantly, and unlike chlorine, both forms of bromine are sanitizers, meaning that they can kill bacteria, algae or other living organisms in the water. When using Bromine as a hot tub chemical, be sure to use a test kit that measures the total bromine, since that is the best indicator of the level of sanitizer in your water. The ideal concentration of total bromine in a hot tub is 4 to 6 ppm.

Water Balance: When using bromine as a hot tub chemical sanitizer you must maintain the Total Alkalinity and pH of the water within the following range since, outside this range the sanitizing effect of the bromine is  reduced (albeit the problem is not as great as when using chlorine).
