Ph Control; Sanitizing; Other Additives - Jacuzzi J-460 Owner's Manual

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 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. 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.

13.3 Other Additives

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.
