Brominating tablets, commonly called BCDMH (1-bromo-3-chloro-5,5-dimethylhydantoin)is the most popular method of
pool bromination. As the brominating tablets dissolve, both hypobromous acid and hypochlorous acid are released,
hence the excellent disinfection properties of the compound. On contact with microorganisms and other organic
content, hypobromous acid gets converted into the inactive form or spent bromine. Hypochlorous acid reacts with the
built up spent bromine and converts it back to the active sanitizing hypobromous acid form. Although chlorine is
continuously being added to the water in the form of hypochlorous acid, hypobromous acid is the primary disinfectant
and oxidizer.

FEATURES
Works continually to kill bacteria – The hypobromous acid released when the tablets are dissolved in water
works continually to kill bacteria, control algae and oxidize the organic contaminants in water.
Gentle on pool equipment and surfaces.
Ideal for indoor pools – Unlike chloramines, bromamines formed when hypobromous acid comes in contact
with nitrogen compounds and other swimmer wastes are excellent disinfectants.
No irritating odors – Bromamines do not give rise to irritating odors like those produced by chloramines and
are therefore well suited for indoor pools.
Reduced eye irritation – Brominating sanitizers cause very minimal eye irritation.
Clears up hazy water and helps prevent algae growth.
No breakpointing required – Breakpointing or shocking a bromine system to eliminate the bromamines is not
necessary as they form effective biocides, occasional shocking is sufficient.

APPLICATION
Ensure all pool equipment is working properly, backwash filter system following manufacturer’s directions.
Adjust pH between 7.2-7.6 and establish a bromine or chlorine residual of 1-2 ppm in the pool.
If residual is established with brominating tablets in a brominator, use the brominator at the highest feed rate.
Once bromine residual reaches 1-2 ppm, adjust the feeder accordingly.
To maintain bromine residual, adjust the brominator feed rate to assure a constant treatment level of 1-3 ppm
in residential pools and 3-5 ppm in commercial pools.
Use a test kit or test strips regularly to maintain the bromine residual in the water.
