12.0 Water Quality Maintenance

To decrease the risk of contracting a waterborne illness (e.g. an
infection, bacteria or virus) and/or respiratory ailments, maintain water
quality within specified limits. This will enhance your enjoyment and
prolong the life of the hot tub's equipment. Doing so requires regular
attention because the water chemistry involved is a balance of several
factors. Procrastination in regard to water maintenance will result in poor
and potentially unhealthful conditions for soaking and even damage
to your hot tub investment. For specific guidance on maintaining
water quality, consult your Authorized Sundance Spas dealer who can
recommend appropriate chemical products for sanitizing and maintaining
your hot tub.

ment bay. The equipment bay may reach elevated temperatures,

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
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 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 sanitizer.

Sanitizing

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. SunPurity™ mineral cartridge designed
