BROMINE
There are two types of bromine systems. One type is a solid tablet form
that is added to a skimmer and feeds sanitizer into the passing water as it
slowly dissolves. It contains both bromine and chlorine. The function
of the chlorine is to make more bromine when none remains. The second
type uses a bromide salt which requires the addition of a separate oxidizer
such as chlorine, ozone or non-chlorine shock.
When bromine is added to water, it forms free bromine. Like chlorine, free
bromine can also combine with ammonia compounds, but the combined
bromine reacts as quickly as free bromine. Thus, there is no need to
distinguish between free and combined bromine. A bromine system
should be shocked with 10 ppm of chlorine periodically. Spa owners may
need to do this frequently. Check with your local chemical supplier for
advice.
Determine bromine readings by using pad 1 on the test strip. Note: the
magenta (hot pink) values represent the bromine test results, and are
found just below the free chlorine values printed in black.

The ideal range for bromine in pools
and spas is 3-6 ppm.
