Maintaining proper chemical levels in a hot tub is necessary at all times. There are several methods available for treating the water in a hot tub. Care and testing is required to ensure the hot tub water is clean, clear and safe. A bromine solution may be one method for you to consider.

Bromine is very similar to chlorine. Bromine tends to build up in the water and needs to be reactivated with a shocking treatment chemical such as potassium mono persulfate or potassium peroxy monosulfate. Too much bromine can result in equipment damage. Care must be taken to keep bromine levels in check.
How Bromine Works
Bromine works by killing microorganisms and bacteria by attacking their cell walls through oxidation. It destroys the enzymes and structures inside these cells.
Bromine is an excellent sanitizer and inexpensive method to use. There are floating bromine feeders available that hold bromine in tablet form. This is a very convenient and effective way to sanitize your spa. Easy to use bromine test strips are readily available from your local spa dealer to keep the proper bromine levels.
One of the disadvantages to using bromine is that there is an odor present. Also, many people have sensitivities to bromine that can lead to itchy and dry skin. Bromine degrades from exposure to sunlight. Bromine also requires frequent testing and adjustments to ensure the chemical remains in the proper levels.
Proper Bromine Levels
Proper bromine levels maintained in spa water should be from 4 to 6 ppm. When performing a shock treatment, more bromine may need to be added. Bromine levels should be over 10 ppm at this point, but you should wait until the levels of bromine reduce to below 10 ppm before you use the spa.
