14.1 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 hot tub water, it is very important
to maintain a slightly alkaline condition of 7.4 to 7.6 pH. Problems
become proportionately severe the further outside of this range the water
gets. A low pH will be corrosive to metals in the hot tub 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 hot tub clean
is severely affected as the pH moves beyond the ideal range. That is
why almost all hot tub water test kits contain a measure for pH as well as
sanitizer.
14.2 Sanitizing
To destroy bacteria and organic compounds in the hot tub water, a
sanitizer must be used regularly. Your Sundance hot tub is equipped with
the Brominator™, a special compartment built into the floating skimmer
gate to hold bromine tablets. By regulating the number of bromine tablets
in the Brominator™ you can control the amount of bromine which is
actively working in your hot tub water. A bromine residual of 2.0-4.0 ppm
is generally considered desirable. A two-part bromine system or granular
chlorine (dichlor) are also acceptable sanitizers.
IMPORTANT: Do not use chlorine tablets (trichlor) in your hot tub.
This chemical can have an extremely corrosive effect on certain
materials in the hot tub. Damage caused by use of this chemical,
or improper use of any chemicals, is not covered under the hot
tub’s warranty.
14.3 Other Additives
Many other additives are available for your hot tub. 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 Spas dealer can advise you on the use of these
additives.
14.4 Ozone Water Maintenance System
This system is optional on North American models and standard
equipment on export 50 Hz spa models. If your spa is equipped with the
Sundance CD Ozone water purification system you will find that your
water stays fresh and clear with significantly less chemical sanitizer
