Using Chlorine as a Sanitizer
If you choose to use chlorine as a sanitizer, only
use granulated chlorine, not liquid chlorine.
Once a week, check the chlorine level using either
a test strip or a reagent kit. See the table on the
following page for the ideal range.
Add one or two tablespoons granulated chlorine to
the spa water weekly. Note that chlorine dissipation
rate will be faster at higher water temperatures and
slower at lower temperatures.
When you add chlorine, open all of the jets and run
the spa at high speed with the cover open for at
least 30 minutes.
Follow the maintenance schedule on page 30.
Sanitation
Sanitizers kill bacteria and other organic waste by breaking them down to
non-harmful levels and are ltered out. Before you ll your spa, you need
to decide which chemical sanitizer you wish to use. Consult your Cal Spas
dealer for the right decision with regards to your lifestyle and spa usage.
We recommend either bromine or chlorine as your sanitizer. Both work well when maintained regularly.
DO NOT use trichlor. Trichlor is very acidic and the hot temperature of the spa causes it to
dissolve too quickly. It will cause damage to your spa and will void your warranty.
Whichever plan you decide on, follow it completely and don’t take shortcuts. It will provide you with clean,
safe, clear spa water with a minimum of effort. Spa owners with an ozonator still need to use a chemical
sanitizer. See page 27 for instructions on usage.
Using Bromine as a Sanitizer
Bromine is a very effective sanitizer that produces
low chemical odors. Unlike chlorine, it can break
down bacteria and other impurities to a safe level
with a low burn-out rate.
Bromine is available in both granulated and tablet
form. Use granulated sodium bromide to establish
your bromine base. Use tablets to maintain it.
When you begin with fresh water, add 2 ounces of
granulated bromide. Open all of the jets and run
the spa at high speed with the cover open for at
least 30 minutes. This is your base bromine level as
the tablets will take a while to dissolve.
Place three or four bromine tablets in your chemical
oater.
Follow the maintenance schedule on page 30.
