I read Ben's post mentioning PB but want to make sure this will work:

Mom's giving up on PB having seen the spectacular results of BBB in my own pool. She has a trustworthy local pool store that's not trying to push anything on her and yesterday, on my request, tested her water for Cu. They came back with a number, .65. I don't kinow what the refers to, maybe someone here can say.

I've already set her up with the bleachcalc (Thanks again and again, Mike!) and she's ready to pull the trigger with 12.5% Cl. I just want to be sure there's nothing else she needs to do to know about vis-a-vis the PB history.

I'm not posting any other numbers since I'm already comfortable with the process having done BBB for over a hear now. Needless to say, she has 0 TC and 0 CYA.

Thanks!
