Pro-Tip

Bromine doesn't 'burn off' in UV light as fast as chlorine, making it the preferred choice for outdoor spas. However, once you have a 'Bromine Bank', you cannot easily switch back to chlorine without a full drain.

Frequently Asked Questions

Can I switch?

Yes, but you usually need to drain and refill to completely remove bromine 'bank'.
