becareful.. Cupric Sufate is a poison. It can be used to get the algae out
of a pond by dragging a bag of it up and down the pond , and it is a great
aid when you get white phosphorous on your finger , it plates copper on the
phosphorous so you can go to the hospital and explain to the homeland
security folks why you have it on your finger in the first place. Just be
extremely careful with it.

I was searching past postings for info on causality, preventon, and
cure for Hydrogen Sulfide. One poster last spring (link below)
suggested using copper sulfate as a final remedy.

I have some Merlot that has otherwise been looking great; good sugar
and acid, good color, good palate - but is carrying the dreaded rotten
egg odor. I have racked with moderate aeration; but am wondering what
remedies might still be there if another racking or two doesn't fix the
problem. Does CuSO4 work? What amounts - and how to add?
