If what is wanted is copper sulphate, then the least expesive
source for it is usually a hardware or feed store, as Barbara
mentions. It is used to: clean roots from drain systems, and
often in lakes/ponds to control algae growth. Note that I did
not say it was a good IDEA to use it for that, but it is so used.

I believe what you're trying to find is copper sulphate. You can
find it at
a hardware or feed store. I think it is a type of fertilizer.

Hmmmmm. Well, I'm an essentially non-chemistry person myself,
barring the odd bit of glaze chemistry from time to time.
But I tend to look askance at chemicals added to water to control
weed/algae growth when that water is used for livestock, wildlife,
and to raise pan fish in, etc. I may eat those pan fish, time to
time. And I have this (unscientific; no data) notion that it
winds up in the water table eventually. I was, in essence, merely
reporting how I had observed copper sulphate to be used, and my
doubts about the wisdom of some of said uses.

Dannon:
Copper sulphate, called Bluestone, was used to keep the water free of
algae in swimming pools. A few cups of the stuff was put into a burlap
bag and hung in the pool. Used to make the kids with very blond hair
develop a slight green cast. Don't know of any who died from it.
I use it in concentrated form to destroy roots in my leach lines.
Copper sulfide is used as a fertilizer.
