Both bromine and chlorine are chemical compounds that serve a similar purpose: they decontaminate pool and spa water by killing off bacteria. However, these chemicals differ in the way they clean, react to temperature and interact with skin. If you're considering bromine vs chlorine for use in a pool or spa, our guide will help you choose …
Bromine
Volatile organobromine compounds are capable of surviving in the atmosphere long enough to reach the upper ozone layer where their bromine atoms are 50 times more damaging than the chlorine atoms - which are the main threat, coming as they did from the widely used chlorofluorocarbons, the CFCs.

Bromine Compound
Bromine and chlorine compounds are the most generally used halogen-containing flame retardants because iodine compounds are not sufficiently stable and fluorine compounds are too stable to be useful. Halogen-containing flame retardants act primarily in the gas phase as hydrogen halides inhibit the radical-chain oxidation reactions in the flame.

Bromine can also be found as an alternative to chlorine in swimming pools. Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire). Some bromine-containing compounds were historically used as sedatives (drugs that can make people calm or sleepy).
