OK. I didn't realize you were using the / key to mean divide. Wasn't even thinking of that. And, of course, dividing by 2 is the same as multiplying by 0.5.

No way to get rid of CC except to continue shocking the pool. Stabilizer will not take care of it. CC is the combined chlorine --- meaning chlorine that has been "used up" sanitizing something in the water. You want it to be 0. Just keep hitting it with bleach. I hope by Sunday you can swim. There is no way to know if it will be ready by then. The only thing I can say (and I know I've said it before) -- the more times you test and shock the faster it will go. If you are home from work, do it every hour or two if you can. A pain in the butt, yes, but it will speed it up.

(To clarify something you asked several days back in this thread regarding 3 types of chlorine readings. One of them, CC, I explained in this post already. FC = free chlorine. This is the chlorine that is still available to be used sanitizing your water. TC = total chlorine and is the sum of FC + CC.)
