Copper in Tri-Chlor?

I'm interested in this because I use a few tablets a month to maintain CYA in the summer.

From my reading of the linked discussion, it doesn't seem to suggest that ALL tablet, granules and sticks have copper, but some certainly do. It's also probably fair to say lots of tri-chlor tablets have copper in them, based on the fact that I always see Clorox XtraBlue tablets in stores like Home depot, lowes, costco, etc... It makes me a little sad. In the same list, it shows Algaecides, which again some algaecides do contain copper, but PolyQuat60 doesn't

Demegrad9 has it correct.

It is in some, but not all forms of trichlor. Is it in the majority??? I am not sure but be sure to look before you buy the tabs, etc.
