Hey all. I've recently started up our new (used) hot tub and thought I was doing quite well with it. I've been doing the 3 step bromine sanitizing system. Unfortunately I'm finding myself with very high bromine readings lately. I've been using the FAS/DPD test from my TF100 pool test kit to test bromine levels. As advised by ChemGeek, I've been multiplying my results by 2.25 to adjust for bromine. Today it took about 17 drops in 10 ml of sample water to turn it clear again. That'd be 8.5 if it were chlorine, but over 19ppm in bromine. This is with only having the floater open one little notch.
I wasn't sure if the spa had an ozonator or not, as I'm not sure what one looks like. When I was adding insulation and hooking the tub up, I did notice that a small wallet sized control box which had something about ozone on it was present, but I assumed there would be more to it than just that little box.
So, do I have too many pucks in the floater? Is the pool floater (all they had at walmart) too big for the spa? Or is the floater unnecessary if I have an ozonator?
Any other ideas or suggestions?
