CHEMICALS & ADDITIVES
Water chemistry balance is extremely important in maintaining good water quality and the preserva-
tion of spa equipment. It is a simple task to maintain your spa chemistry in balance. It must be done
on a regular basis. The 2 parameters that have to be maintained are the pH and chlorine content.
pH BALANCE
: pH is a measure of water acidity. On a scale of 0 to 14, the neutral point of balance
is set between 7.2 and 7.6. A measure below 7.2 indicates that spa water is more acid. Such a condi-
tion results in corrosion to spa equipment metal components. Above 7.6 means that spa water is
more alkaline. This causes salt deposits, and scaling in the equipment and in the spa. Both condi-
tions are detrimental and can cause damage.
CHLORINE / BROMINE
: One of these sanitizers must be used to remove bacteria and other
organic matter from the spa. Not high enough amounts of sanitizer causes water to turn green and
unhealthful. A high level makes water smell pungent, irritate the eyes and the skin and can cause
damage to the metal components of the spa equipment.
Do not use types of chlorine which are not designated for spa use. Specifically do not use chlo-
rine intended for pool use.
The booklet that came with your spa’s chemical kit contains detailed procedures for maintaining spa
chemistry. Your dealer stocks a variety of chemicals to maintain spa chemistry and can help you in
the selection of the right chemicals and their methods of application.
A number of other additives are available to enhance spa usage. These include additives to remove
dissolved metals, reduce foaming, remove body oils, some make the water feel and smell better.
Your dealer can help you select the right additives.
Chlorine vs Bromine
: Both these sanitizers if properly applied will maintain a sanitary spa. There
are pros and cons on both sides, but the choice is up to the user. Please note these sanitizers are
caustic, excessive dissolved amounts of which will cause damage to the spa equipment. It is there-
fore necessary to maintain the proper balance by periodic measurement of sanitizer content.
