12.0 Water Quality Maintenance

Maintaining the quality of the water within specified limits will serve to
enhance your enjoyment and prolong the life of the spa's equipment. It
is a fairly simple task, but it requires regular attention because the water
chemistry involved is a balance of several factors. There is no simple
formula, and there is no avoiding it. A careless attitude in regard to water
maintenance will result in poor and potentially unhealthful conditions for
soaking and even damage to your spa. For specific guidance on main-
taining water quality, consult your authorized Sundance dealer who can
recommend appropriate chemical products for sanitizing and maintaining
your spa.
CAUTION: Never store spa chemicals inside the spa's equipment
bay.

12.1 pH Control

pH is a measure of relative acidity or alkalinity of water and is measured
on a scale of 0 to 14. The midpoint of 7 is said to be neutral, above which
is alkaline and below which is acidic. In spa water, IT IS VERY IMPOR-
TANT TO MAINTAIN A SLIGHTLY ALkALINE CONDITION OF 7.4 to 7.6.
Problems become proportionately severe the further outside of this range
the water gets. A low pH will be corrosive to metals in the spa equipment.
A high pH will cause minerals to deposit on the interior surface (scaling).
In addition, the ability of the sanitation agents to keep the spa clean is
severely affected as the pH moves beyond the ideal range. That is why
almost all spa water test kits contain a measure for pH as well as sani-
tizer.

12.2 Sanitizing

CAUTION: Do not use chlorine tablets (trichlor) in your spa.
This chemical can have an extremely corrosive effect on
certain materials in the spa. Damage caused by use of this
chemical, or improper use of any chemicals, is not covered
under the spa's warranty.
To destroy bacteria and organic compounds in the spa water, a sanitizer
must be used regularly. Chlorine and bromine are the two most popular
sanitizers used to date. Many other additives are available for your spa.
Some are necessary to compensate for out-of-balance water, some aid
in cosmetic water treatment and others simply alter the feel or smell of
the water. Your authorized Sundance dealer can advise you on the use of
