Using Chlorine as a Sanitizer
If you choose to use chlorine as a sanitizer, only use granulated chlorine, not liquid chlorine. We recommend
you use only Cal Spas “Chlorinating Granules”.
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 Cal Spas “Chlorinating Granules” 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 36.
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 and use only Cal Spas brand chemicals.
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 tablet form. Use granulated bromine to establish your bromine
base. Use tablets to maintain it. The lter cartridge provided with your spa has an internal chamber for bro-
mine tablets. Do not use a oater.
When you begin with fresh water, add 2 ounces of Cal Spas Go Brom. 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.
Add two ounces of Oxidizer Shock. Open all of the jets and run on high speed with the cover half open for
at least 30 minutes.
Place three or four bromine tablets in the chamber inside the lter cartridge.
