Copper in Tri-Chlor?

[sktn77a]

Just received an e-mail from TFP pointing to an article stating the copper is found in tri-chlor tablets, granules and sticks:

While some sources ("Blue") may contain copper, I'm not aware that it is in the majority of tri-chlor tablets, granules or sticks?

Comments?

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.
