Okay I have read extensively on the chemistry and testing of Bromine and have to say I am now crosseyed and feel really dumb. There is a reason I am an accountant and not a chemist - I just don't get it, so can someone help me with the Bromine Testing for Dummies version. I don't need to know the how's and why's, just what exactly to do. We don't use the spa much and I don't have time to test/treat daily, really want to get to once a week maintenance plus what needs to be done when used.
455 gal fiberglass free standing hot tub w/ozonator
New fill on 5/20 with sodium bromide
using floating bromine tabs
No use since new fill
I have the TF-100 kit which I have mastered for my salt water chlorinated swimming pool, I believe I can use this kit also for my Bromine hot tub. If I understand correctly all I have read before, I test pH, TA and CH exactly the same as my pool, no need to test CC, CYA and Salt. It's just the FC (or Bromine) testing I'm unsure about. Yesterday I used the R-870/R-871 and it took 21 drops to clear the red - so does this mean CL of 10.5 (if it were my pool) and BR of 23.6 (multiply the result by 2.25)?
Also can/should I use borates in the spa?
