Hot Tub Sanitizers

How often do you think about sanitizing your hot tub? I bet not as often as you should be. This is the one thing that keeps bacteria and algae from forming in your hot tub, so it’s important to keep up with it. There are two types of sanitizers: chlorine or bromine. Both work well, but some people prefer using chlorine because they don’t want to use chemicals in their water. They also like how quickly the chlorine dissipates into the air after it has done its job of killing any harmful organisms in the water. If you’re someone who wants a more natural option then go ahead and try out our bromine-based or another sanitizer!
