proper strength or type for your spa. Use of the wrong chemicals can be
dangerous and may void the warranty on your spa.
WATER TESTING
It is recommended that you test your spa water regularly with an accurate
test kit or test strips. These are available from your local Authorized
Dimension One Spas dealer. Also, be sure to follow manufacturer's
instructions for chemical use.
PH CONTROL
All water solutions have pH, which is a measure of the acid to base rela-
tionship. While a pH reading of 7.0 is considered neutral, a lower read-
ing is considered acidic and a higher reading is basic. The proper pH for
spa water is between 7.4 and 7.6. High pH (above 7.6) can reduce sani-
tizer efficiency, cloud the water, promote scale formation on surfaces and
equipment, and interfere with filter operations. When pH is too high, add
a pH decreaser. Low pH (below 7.2) is equally damaging and can cause
equipment corrosion, water that is irritating, and rapid sanitizer dissipa-
tion. Add pH increaser to adjust the level.
NOTE: Never add more than 3 teaspoons of pH adjuster per 250 gallons
of water. Always add adjuster with jets operating and circulate all chemi-
cals for at least 30 minutes. Remember that good pH control and saniti-
zation are absolutely essential for proper spa water treatment.
SANITIZER
The importance of maintaining an adequate level of sanitizer in your spa
cannot be overemphasized. Warm water presents a fertile environment
for the growth of bacteria and virus. This growth is prevented when ade-
quate sanitizer levels are continuously maintained.
***WARNING***
Sanitizers such as Tri-chlor (tablets or sticks), calcium hypochlorite, sodi-
um hypochlorite, and any chemical which dissolves on or remains undis-
solved in contact with the spa surface will damage your spa and will void
the warranty completely.
