BROMINE (BROMINE CANNOT BE USED WITH THE VISION
SYSTEMS)
Bromine is the most common sanitizer used in spas. Bacteria can be
controlled by maintaining a proper total bromine level of 3.0 to 5.0 ppm.
Brominating tablets are a convenient and effective source of bromine for
your spa. Do not drop bromine tablets directly into the water as this
may damage the spa surface. A bromine "floater" will safely and properly
dispense the tablets for you or you may purchase the Dimension One
Spas Adjustable Bromine Feeder from your local Authorized Dimension
One Spas dealer. When used properly, brominating tablets will keep
your water clean, clear, and odor free. To ensure maximum effectiveness,
add a 1/2 ounce of sodium bromide per 100 gallons of water every time
you fill your spa. This will establish a bromine reserve.
CHLORINE
Chlorine can also be used as a water sanitizer, however, it is highly sensi-
tive to pH. To be effective, you must have a spa pH range of 7.4 - 7.6.
Any reading outside this range will greatly reduce the chlorine's effec-
tiveness.
Use your chlorine test kit or test strips to maintain a reading of 1.0 - 3.0
parts per million (ppm) of free chlorine. If the reading is below 1 ppm,
the level should be raised before the spa is used. If the reading is above 3
ppm, it should be allowed to drop to the proper range before use. Read
the instructions on your chlorine container carefully, or consult your
local Authorized Dimension One Spas dealer if you are having difficulty
adjusting your chlorine level.
The best chlorine for your spa is a granular "Dichlor" compound. It dis-
solves quickly in moving water and has a nearly neutral pH. Add chlo-
rine while the jets are running and let the jet system run for 1/2 hour.
Generally, heavily contaminated water can be disinfected using large
chlorine doses, in the range of 8 - 10 ppm, but a more practical method
is to drain the spa and refill it with fresh water.
The effectiveness of chlorine is decreased when the cover is left off the
spa for two reasons: (1) sunlight decays chlorine rapidly and (2) organic
debris blown into the spa taxes the effectiveness of the chlorine. In
addition, the higher the water temperature, the faster chlorine will
decay.
