MAINTENANCE
Water Chemistry
Water chemistry is critical in a spa system.
Chemicals are used to sanitize the water and
control the pH balance. The combination
of high water temperature and small water
volume means that the chemical balance must
be watched carefully. It is recommended that
you purchase a chemical start up kit, and
the additional chemicals needed to maintain
the proper/optimum chemical balance, from
your dealer.
Sanitizing
Sanitizing the water destroys harmful
organisms and keeps your spa healthy and
safe. Three commonly used spa sanitizing or
oxidizing agents are bromine, chlorine and
ozone. Chlorine or bromine are chemicals that
you add to the water. Ozone is a gas that is
produced by an ozonator and injected into
the water. It is important that a residual of
sanitizer remain in your water. High water
temperature, aeration and use will increase
the need for sanitizer.
In addition to maintaining a residual,
it is important to ‘shock’ your spa water
periodically and after heavy use. This addition
of substantial amounts of sanitizer super-
chlorinates the water and oxidizes non-
lterable organic residue. Allow the sanitizer
level to drop back to the residual amount
before using. Also use your Clean Up Cycle
heavy use for additional ltration. Tests should
be done daily with your test kit to keep a
chlorine or bromine residual of 3.0 to 5.0 ppm.
pH Level
pH is the balance of acidity and alkalinity
in the water. Maintaining proper pH is
important for the eectiveness of your
sanitizer, for user comfort, and to prevent
corrosion of the spa equipment.
Caution: Never mix two chemicals together.
Caution: Never store chemicals in the
equipment compartment.
Caution: Do not use muriatic acid to balance
pH as it will damage your spa surface and
equipment.
Recommended Levels
pH: 7.2–7.6
(Ideal 7.4–7.6)
Sanitizer Residual: 3.5–5.0 ppm
Total Dissolved Solids: 100–200 ppm
Free Available Sanitizer: 3.0–5.0 ppm
Total Alkalinity: 80–100 ppm
ideal for dichlor,
trichlor, and
bromine
NOTE: Make sure you use fresh test kit
strips/chemicals. Test kits and test
chemicals should be stored in a cool,
dry location. Check the manufacturer’s
instructions to determine shelf life and
expiration date.
Water maintenance with the
Ozone or UV Water Treatment System
Equipping your spa with an Ozone system
that includes the Ozonator or UV Sanitizer
is a smart decision. The use of ozone in
conjunction with spa sanitizing and water
balancing chemicals helps to provide you
with a cleaner, healthier spa, reduces chemical
usage, and protects your skin from chemically
induced irritation.
