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. Procrastination in regard to water maintenance will result in poor and
potentially unhealthful conditions for soaking and even damage to your spa
investment. 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. 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. Your Jacuzzi spa 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 spa 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 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.
