WATER QUALITY MAINTENANCE
General Information
As the owner of a Conquest 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 components
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 .
Test pH weekly.
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 .
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 bisulfate at the rate suggested
on the container . After initial application, allow water to circulate approximately 20 minutes
on "Jets1" at high speed . Test pH and add second dose if required . (Conquest Spas "Jets1"
operates 15 minutes)
Total Alkalinity
There are minerals in your spa water that act as buffering agents . Total alkalinity is the
measurement of these alkaline materials that help prevent corrosion and staining . The correct
amount of alkalinity in your spa water will keep the water’s pH consistent while allowing for
economical pH adjustment when necessary .
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 .

OWNER'S MANUAL
Example: At low total alkalinity levels, the water’s pH easily drifts, making frequent pH
adjustments necessary and the added expense of multiple chemical treatments .
On the other hand, a high total alkalinity level keeps the water pH rigidly fixed . If pH
adjustment is necessary, you will need unusually large amounts of treatment chemicals
to change the water’s pH .
Recommended Range: 80 to 120 Parts Per Million (PPM)
Potential Problems:
1 . pH difficult to maintain . If total alkalinity is too low, pH will drift .
2 . Corrosive tendencies . If total alkalinity is too high:
• pH difficult to adjust (it remains fixed .)
• Cloudy water .
• Potential for scaling .
• High pH and low sanitizer efficiency .
TESTING WEEKLY
Adjusting Total Alkalinity
Total Alkalinity can be raised with Alkalinity Increaser, or sodium bicarbonate at the
manufacturer’s recommendation for dosage .
Calcium Hardness
Calcium hardness is the amount of dissolved calcium in your spa water . Too little calcium in the
water will etch plaster surfaces, too much will leave deposits on surfaces and equipment .
Recommended Range: 125-150
Potential Problems:
Calcium Hardness Too Low
• Some surfaces may be etched .
• May lead to equipment corrosion .
Adjusting Calcium Hardness
Raise hardness by the addition of calcium chloride . Decrease calcium hardness by draining spa
and replacing with water containing lower levels of calcium hardness .
Disinfectant
• Brominating Tablets, Granular Bromine and Granular Chlorine are popular disinfectants and
are particularly well suited to compliment your ozone purification system spa . They are also
very suitable products in water with elevated temperatures .
• Brominating Tablets and Granular Bromine are effective as a spa water sanitizer and
disinfectant . Follow manufacturer’s directions for proper dosage . It is recommended to
maintain an active bromine residual of 2 .0 to 4 .0 ppm .
• Granular Chlorine (Dichlor Dihydrate, Lithium Hypochlorite), is designed to dissolve
quickly and completely, provide a steady source of available chlorine to control the growth
of algae, kill bacteria and destroy organic contaminants . It is recommended to maintain
a chlorine residual of between 1 .0 and 3 .0 ppm . Non-Chlorine type shock will oxidize or
destroy most of the organic contaminants that result from bather load . This quick acting
oxidizing shock treatment goes to work almost immediately improving water quality and
eliminating irritating wastes and odor . This product is intended to be a shock treatment
only, and is not a disinfectant .
Calcium Hardness Too High
• May contribute to cloudy water .
• Scaling of surface, piping and equipment .
Note:
The use of Biguanide, Salt
generators and other after market
sanitizer/ disinfectant systems may damage
components and void your spa's warranty.
