Welcome to our forum.
up until recently we had been adding about 2 tbls everyday with not very much rhyme or reason other than noticing an unbalanced reading on a strip (then adding chems to get it to read ok)
Quoteup until recently we had been adding about 2 tbls everyday with not very much rhyme or reason other than noticing an unbalanced reading on a strip (then adding chems to get it to read ok)WOW!!!   That's a lot of chlorine and it could be a hypersensitive spot on your skin that has broken out.  It could take a while for that rash to settle down.  Have you seen a dermatologist?   In the meantime try this for your sanitizing system,   1  1 teaspoon per bather added after you soak  2  shock with MPS once a week on a schedule  3  adjust PH and Alkalinity accordingly  4  test for CYA and hardness once a monthThis is pretty much the system that most on this site use,  you can adjust to suite your own needs.  By adding dichlor after each soak to a level of about 3 to 5 ppm(after 20 minutes), the next time you use the tub the chlorine level is almost at zero.   During periods of low use you can add a teaspoon once every couple of days to keep the tub sanitized Good luck and I hope the rash clears up
I know this sounds idiotic. I'm pretty sure I was WAY overcomplicating the chems and testing and everything because of the rash, which never allowed us to get in a regular sanitizing routine..we were always troubleshooting instead of just maintaining.
I know..it's only recently that I've grasped the concept that the test strip doesn't have to be in the  "ok range" for sanitizer before you get in it. It's just that I was so freaked about the possibility of their being bacteria somehow in the tub that I thought more was better.. wrong.I know this sounds idiotic.
