Water Quality Maintenance
GENERAL INFORMATION
As the owner of a spa, endless hours of entertainment, recreation, and relaxation await you.
Caring for your spa will become a routine and pleasant part of your daily activities. You will be
able to maintain your spa water and keep your spa equipment in excellent condition. To do so
you first must balance your spa’s water.
BALANCED WATER
Balanced water ensures spa bathers’ safety as well as protecting the spa heater and compo-
nents from corrosion. Also, balanced water protects the spa surface from unsightly scale
deposits which reduce the efficiency of the spa equipment. You can obtain balanced water by
correctly adjusting a few chemical components in the water. Specifically, you will need to adjust
the pH, total alkalinity and calcium hardness
NOTE:
Improper water chemistry can result in product failure and invalidate your warranty.
PH
pH is measured on a scale that runs from 0-14. pH indicates whether water is neutral, acidic, or
basic.
The drawing below shows a pH equal to 7.0 is neutral. A pH below this point is acidic and a pH
above this point is basic.
RECOMMENDED RANGE - 7.2 to 7.8
If the pH is too low it can
1. Corrode metal surfaces.
2. Use excess sanitizer.
3. Irritate bathers’ skin and eyes.
If the pH is too high it can
1. Deposit scale on surfaces.
2. Contribute to cloudy water.
3. Cause eye irritation.
4. Reduce sanitizer efficiency.
TEST pH WEEKLY
ADJUSTING PH
To raise pH add a granular pH Increaser or sodium carbonate at the rate suggested on the
container. To lower pH add a granular pH Decreaser, or sodium bi-sulfate at the rate suggested
on the container. After initial application, allow water to circulate approximately 15 minutes on
Pump 1 at high speed. Test pH and add second dose if required.
TOTAL ALKALINITY
There are minerals in your spa’s water that act as buffering agents. Total alkalinity is the mea-
surement of these alkaline materials that help prevent corrosion and staining. The correct
amount of alkalinity in your spa’s water will keep the water’s pH consistent while allowing for
economical pH adjustment when necessary.
