WATER CHEMISTRY
CAUTION: The chemicals used to maintain the pH balance of the
water and to sanitize the water can be dangerous. Always follow
these basic guidelines when handling the chemicals
1. Always read and follow the directions on the label, unless directed
otherwise.
2. Never mix different chemicals.
3. Do not exceed the recommended amounts of chemicals—follow the
directions on the label.
4. Keep all chemicals out of the reach of children and pets.
5. Keep containers closed tightly when not in use.
6. Never add water to the chemicals—always add the chemicals to the
water as directed.
7. Always store chemicals in a cool, dry place.
NOTE, Consult your dealer on local weter chemicals as its var-
ies from location to location.
WATER TREATMENT GLOSSARY
1 - Total Alkalinity: Total Alkalinity measures the water’s ability to re-
sist uxuations in the pH level. It is measured in ppm (parts per million)
ranging from 0 - 400 or up. The optimum range for your spa water is
between 80 and 140. This can easily be measured with 3- or 5-way test
strips. With low alkalinity the pH level will be prone todramatic uxua-
tions. With high alkalinity the pH becomes increasingly difcut to ad-
just.
2 - pH (potential hydrogen): The PH is used as a measurement of
the active acidity, the concentration of active hydrogen molecules in the
water. PH is measured on a scale from 1 to 14, the lower numbers
indicating a greater concentration of active hydrogen. While 7, halfway
between base and acid is neutral, the optimum level of acitity for a spa
is between 7.2 and 7.8.
