Thank you both for your response. I'll try the shotglass method tomorrow morning and post a new set of results. Hopefully the stabilizer will be alright.

As for continuing to use the kit as described in my original post - any opinion on sticking with what I've got till I can get Ben's kit, in light of the fact that I can use the "shot glass" method to test for CC?

I glanced at a post from Hulla?, I think, discussing using the Taylor 2006 test kit as a viable alternative to Ben's. It seems I may be able to get that faster online if I am unable to get accurate readings from what I've got. I have to sit and reread the post. See link below. Any thoughts?

Needless to say, Janet, I will not be using my PB for continued maintenance. I have become a Poolforum member!
