Choosing a SanitizerChoosing a Sanitizer
The HTH Spa
™
Product Line offers two types of
primary sanitizers for use in spas: chlorine and
bromine. Choosing a sanitizer comes down to
personal preference. No matter which HTH Spa
™
Sanitizer you select, both our bromine and chlorine
products sanitize effectively when used properly.
Here is additional information about both types of
sanitizers offered in the HTH Spa
™
product line.
Chlorine:Chlorine:
Chlorine is most commonly used in outdoor spas
because it can be stabilized from degradation by
sunlight.
Chlorine is a stronger oxidizer than bromine.
Fluctuations in pH affect the effectiveness of
chlorine.
Bromine:Bromine:
Bromine is most commonly used in indoor or
covered spas because it cannot be stabilized
from degradation by sunlight.
Bromine is not typically used in outdoor
spas, because of the effect of sunlight on its
degradation.
Bromine is not affected by fluctuations in pH.
Bromine can be less irritating to the skin and
eyes.
