water with a high or low calcium content will raise or lower the CH reading of the water.
F. When the Calcium Hardness is within the recommended range, proceed to the next
step.
BALANCING THE pH
A. The ideal pH level for your spa water is 7.4 -7.6.
EN
B. The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline;
those below 7 are acidic. Maintaining the proper pH level is extremely important for:
• Optimizing the effectiveness of the sanitizer.
• Maintaining water that is comfortable for the user.
• Preventing equipment deterioration.
C. If the spa water's pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritating to spa users.
• The spa's equipment may corrode.
If the pH is too low, it can be increased by adding sodium hydrogen carbonate
(pH/Alkalinity Up) to the spa water.
D. If the pH level is too high, the following may result:
•The sanitizer is less effective.
• Scale will form on the spa shell surface and the equipment.
•The water may become cloudy.
• The filter cartridge pores may become obstructed.
If the pH is too high, it can be decreased by adding sodium bisulfate (pH/Alkalinity
Down) to the spa water.
NOTE: After adding sodium hydrogen carbonate, or sodium bisulfate, wait two
hours before testing the water for pH. Measurements taken too soon may not
be accurate.
E. It is important to check the pH on a regular (weekly) basis. The pH will be affected
by the bather load, the addition of new water, the addition of various chemicals, and
the type of sanitizer used.
F. When the pH is within the recommended range, proceed to the final step.
MAINTAINING THE SANITIZER LEVEL
A. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing
unwanted organisms from growing in the spa. At the same time, you don't want too
high a sanitizer level, or it can irritate your skin, lungs and eyes.
B. Always maintain the sanitizer level in your spa at the recommended level.
C. Manufacturer recommends only Sodium Dichloro -s-Triazinetrione (Sodium Dichlor
or chlorine) as a sanitizer.
WARNING: DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl-hydantoin
(BCDMH), or any type of compressed bromine or chlorine, acid or any type of
sanitizer which is not recommended by Manufacturer.
