I assume you don't have a vinyl pool (hence the calcium). But you can also add calcium by using Cal-Hypo temporarily as your chlorine source and that can be had at other places than pool stores.

Nope. CYA is unavoidable with Tri-Chlor and Di-Chlor because the chemistry of them is such that as they dissolve CYA is released. But Cal-Hypo doesn't have that problem. Be careful, though--Cal-Hypo is the most volatile of the chlorines.
Cal-hypo's side effects are it adds calcium, can raise pH, and sometimes can make your water go milky (rarely, and easily fixed). No CYA at all.

I spoke to the manager this morning, and he already knew about this incident - it seems that one of the two employees tattled on himself. To the manager's credit, he was extremely apologetic and told me that they had already been written up. I tried not to make too big a deal out of the whole thing. As a bonus, on the way out, he handed me about $50 of free chemicals! I was really surprised - he didn't need to do that (but it will keep me coming to the store).
