HotSpring Landmark - Sanitizer and Ozone System Care

• 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 to the spa water.
NOTE: After adding 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)
• Baqua Spa
™
(please consult your Baqua Spa
™
manual for instructions on the use of this product).
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 Watkins.
