>Copper is a popular algicide, in much greater quantitites than you'll >get off a couple of PCBs... There's my solution! I'll give it to my friend with the algae overgrown backyard pond! Or pour it into my algae overgrown fishtank! ;-) I've been wondering what to do with it...I've heard that pouring soda (laundry soap) in will cause the copper to precipitate out in a sludge to make it easier to handle. Anyone have any comment on this? Oh, and Marc, of course I checked the MSDS! But like you said, they do tend to be a bit paranoid.
