I've gotten everything under control with the pool, thanks to you all, and now I'm ready to get the hot tub in shape.
Not really sure where to begin....where is the "hot tub school"?
Hot tub is a 500 gallon hot tub, which has been using bromine as a sanitizer, but I haven't added any since I moved in about three weeks ago.
Knowing this, what should my first step be? Test the water? Don't bother using the chlorine test, since bromine was being used?
