Bromine for Spas
Bromine is a common hot tub sanitizer that works well in warm water and can be gentler-smelling for some owners.
Why this chemical is used
Bromine is popular in hot tubs because it remains effective in warm water and is often used with tablets in a floating feeder or inline system.
When it is needed
Bromine systems still need testing, pH control, oxidation, and water changes. Do not mix chlorine and bromine products unless the label and system specifically allow it.
How to use it safely
- Test before adding anything.
- Calculate dose based on actual spa volume.
- Add chemicals separately with circulation running.
- Wait, circulate, and retest before adding more.
- Follow the product label and spa manufacturer instructions.
Small spas are easy to overdose. When unsure, add less, circulate, and retest.
