baLanCIng THe pH
A. The ideal pH level for your spa water is 7.2-7.6.
B. The pH level is the measure of acidity and alkalinity. Values above 7.6 are alkaline; those below 7.2 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 Hot Spring
®
FreshWater
®
pH/
Alkalinity Up, or sodium hydrogen carbonate 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 Hot Spring FreshWater pH/Alkalinity Down, or sodium bisulfate 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 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 for each type of sanitizer.
c. Watkins recommends only the following sanitizers:
• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• Brominating Concentrate
™
(one step granular bromine)
• BaquaSpa
