Chlorine vs Bromine – What’s the Difference?

If you’ve never had a hot tub before or if you still aren’t sure about water care, it can be a bit overwhelming. 

And it’s not your fault. A lot of the chemical brands out there like to make it seem like magic so you get hooked on their product. 

 There are a few key differences in chlorine vs bromine for sanitizing your hot tub.

So here’s a quick breakdown of the most common ways to sanitize a hot tub.

Every hot tub needs some kind of sanitizer that kills contaminants in the water. 

Without going deep into the chemistry component (it’s been a while since high school chem for me, to be honest), the two most common ways are with chlorine and bromine. 

Chlorine  – the most common hot tub sanitizer

Chlorine is the more common sanitizer and it is a little less expensive.  

However, it is less stable and doesn’t last as long. 

You also get a bit of that chlorine smell when it attaches itself to contaminants. 

Also, if you use too much of it, it can be hard on the skin. 

Bromine – the more efficient and stable sanitizer for your hot tub

Bromine is the more expensive of the two, but it is more stable and lasts longer. 

It’s easier on the skin and you don’t get that chlorine smell as well. 

The beautiful thing about bromine is that it can regenerate. 

So as long as your bromine levels are overall good in the tub, you can use an oxidizer, also known as “shock” to regenerate the bromine in your tub. 

This is a big difference from chlorine, which does not regenerate and you need to continually add it over time. 

Hope that helps and you have an awesome day!
