Yeah I meant no copper too, but I thought that was a given. Brass is what most people get fooled with. Your buddah's just going to dissolve and disappear if you keep it in there, salt water is really corrosive on most metals. If you want shiny coins try some gold or silver foil wrapped around a frag plug. I think aluminum is safe for reefs. I don't know how it'll withstand the saltwater though.
