It may be a little OCD, but I want to test the bromine level (and maybe other stuff) for the private hot tub when I am on vacation using my timeshare. Anecdotally, I've heard that the maintenance of those can be a little off. I use chlorine at home and I don't really know a whole lot about bromine and above ground spas. My understanding is that they are using bromine, though I will double check that. Can I use the Chlorine reagent in the Taylor Basic OTO test, for Bromine testing, or do I need to buy a different reagent? I also have the full test kit, so if that would be more suitable, I can bring that with me instead. What kind of number range am I looking for?
