13.0 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 maintaining water quality, consult your authorized Jacuzzi
dealer who can recommend appropriate 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 7.4 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 the 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 cosmetic water treatment and
others simply alter the feel or smell of the water. Your authorized Jacuzzi dealer
can advise you on the use of these additives.
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.
