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.

Sanitation

After you fill 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 filtered 

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 floater.
