I agree completely with Joe. Copper sulfate is nasty stuff - and unless
there is a real necessity, I would absolutely avoid it.

The OP was simply asking - "I'm worried about possible H2S, should I rack?"
Clearly this is not a black and white answer; some suggest 'no, wait until
complete or until a smell is noticeable'. For my own part, I have found I
can reduce the incidence of H2S by racking off of gross lees as quickly as
possible.
