Heavy Cleaning Instructions - Laguna Bay Spas Spa Owner's Manual

Water Chemistry Basics
normally remains stable. Adding more water with a low or high calcium content
will raise or lower the CH reading of the water. When the Calcium Hardness is
within recommended range, proceed to the next step.
Step 3.) Balancing the pH
The pH level is the measure of the acidity and the alkalinity. It is imperative
to have a slightly alkaline pH level between 7.4 - 7.6. Problems become
proportionately severe the further outside the range the water gets. Values above
7 are alkaline; those below 7 are acidic. Maintaining proper pH level is extremely
important for optimizing the effectiveness of sanitizer, maintaining water
comfort for the users, and prevention of equipment deterioration.
If the spa water's pH level is too low,
the sanitizer will dissipate rapidly, the
water may become irritating to users, and 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.
If the pH level is too high,
the sanitizer is less effective, scale may form on the
spa and the spa components, the water may become cloudy and filter cartridge
pores will become clogged and obstructed. If the pH is too high, it can be
decreased by adding sodium bisulfate (pH/Alkalinity Down) to the spa water.
After adding sodium hydrogen carbonate or sodium bisulfate.
Wait two hours before testing the water's pH levels again.
Measurements taken
too soon may not be accurate. It is important to check the pH level on a weekly
basis. The pH will be affected by the bather load, the addition of new water, the
addition of chemicals and the type of sanitizer used. When the pH is within the
recommended range, proceed to the final step.
Step 4.) Maintaining the Sanitizer Levels
Sanitizer is extremely important for killing algae, bacteria and viruses and
preventing unwanted organisms from growing in the spa. At the same time, if
the sanitizer levels are to high it may cause irritation to the skin, lungs and eyes.
Always maintain the sanitizer level in your spa at the recommended level for
each type of sanitizer. To keep sanitizer levels in the desired range you should
check the bromine, shock, and pH levels before each use and no less than twice
each week even if the spa is not in use.
Do not use tri-chlor chlorine,
bromo-chlor-dimethyl-hydantoin (BCDMH)
or any type of compressed bromine or chlorine, acid or any sanitizer not
recommended by Laguna Bay Spas.
Heavy Cleaning or Decontamination
On occasion, it may be necessary to "Super Sanitize" your spa. If algae develops,
simply draining and refilling the spa will not kill the algae. It will be necessary
for you to decontaminate the spa before it is refilled.
