Frequently Asked Questions (FAQs)

1. Can you use pool bromine in a hot tub?

But maintaining clean water in a hot tub isn't entirely the same as in a pool. You have two main ways of killing bacteria and maintaining ph levels in your hot tub water. You can use chlorine or bromine tablets.

2. Is it better to use bromine or chlorine in a hot tub?

If you have a spa, bromine has a lot of advantages over using chlorine. It may cost a little bit more, but it lasts longer and does a much better job than chlorine at killing bacteria, especially at high temperatures and high pH levels.

3. Is pool bromine the same as hot tub bromine?

High Temperatures Bromine works better at higher temperatures than chlorine. Above 75°F, bromine remains stable, whereas chlorine is more effective in temperatures as low as 65°F. This makes bromine a better choice for hot tubs and spas, and an unheated pool will be better served by the use of chlorine.

4. Do you need to shock a hot tub if you use bromine?

Spa Tablets So, you don't really need to shock a spa or hot tub to “activate” our bromine tablets. However, I do recommend that all spas be shocked weekly, more for sanitation purposes, but also to ensure adequate conversion of bromide ions.
