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 con-

ditions for soaking and even damage to your spa. For specific guidance

on maintaining 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 mea-

sured 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 CONDI-

TION OF 7

.2 to 7.8. Problems become proportionately severe the fur-

ther 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 sanita-

tion 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 con-

tain a measure for pH as well as sanitizer.

12.2 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. 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 these additives.
