New 450 gl. hot tub w/ corona discharge ozonator Knew we had soft water as you can't wash off soap.
The first fill I completely over-dosed with bromine. I added 2 oz. bromide. Then foolishly filled a floater to the brim with tablets. This went on for 48 hours. Upon further research I read that I really didn't need a floater all the time, just activator. We did get a 2nd filter and rinsed and swapped them for 3 days per the installers advice.
TA was 800, calcium hardness was 0 and the sanitizer was rendering the pH purple. I tried draining 50% of the water but still could not obtain a pH value with my Taylor kit even with adding thiosulfate. The pool supply store also said my bromine was 10ppm, phosphates 1000 and calcium hardness 70.
I drained the tub, rinsed a filter and re-filled using an eco-one hose end filter. I've added NO bromide. Have been adding dry acid.
TA is down to 100 but pH is still giving a purple response. Did a dilute bromine test at the 1.8 ml mark and obtained ~10ppm.
Where is this halogen coming from?? Can the filters trap excess bromine when I OD'd it on the first fill. I'm stuck.....
