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.

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.
