The pH test will tell you if your water is
acidic or alkaline (base). pH is measured on a 14 point scale with 7
being neutral. A pH reading of below 7 would be considered acidic
and one above 7 would be alkaline. THE IDEAL pH FOR A SPA IS BETWEEN
7.2 AND 7.8.
CAUTION:
If the pH is lower than 7.2 the water could start to dissolve the
metal in your spa equipment and also cause irritation to your eyes
and skin. A high pH above 7.8 could result in deposits of Calcium or
scale on the spa and equipment. To raise pH use SPA UP. To lower pH
use SPA DOWN. In a freshly filled spa use pH BALANCE to instantly
raise or lower the pH to the correct range of 7.2 to 7.8. pH BALANCE
SHOULD NOT BE USED IN AREAS WITH A CALCIUM HARDNESS OF 200ppm OR
ABOVE.
