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 of granulated chlorine
to the spa water weekly. Note that chlorine dissi-
pation rate will be faster at higher water tempera-
tures 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 35.
Sanitation
After 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.
Sanitizers kill bacteria and other organic waste by breaking them down to non-harmful levels and are ltered
out.
Make sure you follow all instructions.
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.
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 tab-
let form. Use granulated bromine 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. This is your base bromine
level as the tablets will take a while to dissolve.
Place three or four bromine tablets in the chamber
inside the oater.
Follow the maintenance schedule on page 35.
