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 chem-
istry 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 maintaining water quality, con-
sult your Authorized Jacuzzi Premium dealer who can recommend appropri-
ate chemical products for sanitizing and maintaining your spa.
CAUTION: Never store spa chemicals inside the spa's equipment bay.
13. 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 alka-
line and below which is acidic. In spa water, IT IS VERY IMPORTANT TO
MAINTAIN A SLIGHTLY ALKALINE CONDITION OF 7.2 to 7.8. 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.
13 .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
