MAINTENANCE
Water Chemistry
Water chemistry is critical in a swim spa
system. Chemicals are used to sanitize
the water and control the pH balance.
The combination of warm or 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 of your
swim spa, from your dealer.
Sanitizing
Sanitizing the water destroys harmful
organisms and keeps your swim spa healthy
and safe. Three commonly used sanitizing or
oxidizing agents are bromine, chlorine and
ozone. Chlorine and bromine are chemicals
that you add to the water. Ozone is a gas
that is produced by an ozone generator 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 swim spa water
periodically and after heavy use. This addition
of substantial amounts of sanitizer super-
chlorinates the water and oxidizes non-
filterable organic residue. Allow the sanitizer
level to drop back to the residual amount
before using. Also use your Clean Up Cycle
after heavy use for additional filtration. 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 effectiveness of your sanitizer, for user
comfort, and to prevent corrosion of the swim
spa equipment.
Caution: Never
mix two chemicals together.
Caution: Never
store chemicals in the
equipment compartment of your swim spa.
Caution: Do not use muriatic acid
to balance
pH as it will damage your swim spa surface
and equipment.
Recommended Levels
pH: 7.2–7.6
(Ideal 7.4–7.6)
Chlorine/Bromine 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 Ozone Generator
and Ultra Violet Sanitizer
Your swim spa may be equipped with either
or both the Ozone Generator and Ultra Violet
Sanitizer. These systems treat the water in your
swim spa with a specialized ozone application
and/or the extra sanitizing power of ultra-
violet (UV) light, which in conjunction with
spa sanitizing and water balancing chemicals
