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 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. When adding spa shock (chlorine or non-chlorine) or pH
balancing chemicals activate the jets pump(s) and leave the spa cover
open for a minimum of 20 minutes. By doing this you will allow excessive
chemical vapors to exit the spa, protecting pillows and plastic knobs from
chemical attack.
WARNING:
!
OR ENTRAPMENT!
Never leave your hot tub unattended for any reason while the
cover is open and accessible, especially to small children and
animals!
CAUTION: RISK OF PERSONAL INJURY OR SPA DAMAGE!
Never add chlorine tablets (trichlor) or acid to your hot tub
for any reason! These chemicals may damage components
within your hot tub, burn or irritate your skin, create a rash
and void the manufacturer warranty for your spa.
