BROMINE: While nearly everyone is familiar with chlorine and its role with swimming pools, they may
not be as familiar with bromine. Chlorine and bromine are in the same chemical family, but most experts
feel that bromine is better suited for the hot water application of a spa.

Bromine Level - 3.0 to 5.0 Parts Per Million
The role of bromine in spa water is two-fold. The bromine is both a sanitizer as well as an oxidizer. In
its sanitizer role, the bromine destroys micro-organisms such as bacteria, algae, fungi, and viruses. In
its oxidizer role, the bromine “burns up” organic contaminants such as suntan lotion, body oils,
perspiration, dust, and dirt. As the bromine sanitizes and oxidizes, it is used up. If the spa is allowed to
operate with a low bromine level, the water can become unhealthy and unclean.
The proper bromine level to maintain in a spa is 3.0 to 5.0 ppm. Keeping the level much higher than this
level will waste money and is hard on your skin and swimsuit. Letting the bromine level go too low can
result in unclean and unhealthy water.
In order to keep the bromine level at the right level in your spa, the first thing to do is to add a 2 ounce
packet of SPA SODIUM BROMINE SHOCK to the freshly filled spa. (One 2 ounce packet per 400
gallons.) The SPA SODIUM BROMINE SHOCK helps to establish a bromine residual in the spa.
Each time the spa is drained and filled, add the proper dosage of SPA SODIUM BROMINE SHOCK.
(For more detailed start up instructions, see pages 9 and 10.)
Once the SPA SODIUM BROMINE SHOCK is in the spa, White river Brominating Tablets that you
place in your spa’s bromine float will dissolve and provide the bromine that is needed to keep your spa
clean. Never add bromine tablets directly to the spa as damage may result. You will have to adjust
the amount of water that flows over the bromine tablets in order to control the bromine level. The more
holes that are uncovered on a floating brominator, the more water will flow over the bromine tablets.
The result is a higher bromine level.
FOOTNOTE
1 While chlorine and bromine have many of the same characteristics, bromine is more stable than chlorine in high temperature applications. If chlorine is to
be used on a spa, it should be sodium dichlor granular chlorine. (WHITE RIVER DISINFECTANT for example.) Never use chlorine tablets, liquid chlorine,
or calcium based granular chlorine.
It is also important to note that there are a few spas on which sodium dichlor granular chlorine must be used. These spas cannot safely use bromine
because they use a spa shell material that discolors very easily. The majority of spas, though, use what is referred to as cast acrylic. On a cast acrylic spa,
bromine is an acceptable option.
If your spa did not come from Eastgate Pools, or if you are unsure of your spa’s surface material, please give us a call. We will try to help you determine
which sanitizer is right for your spa.
