I found a 20# base rock on cragslist for $60 dollars, after talking with the seller I found out that the tank it used to be in has been treated with copper about six years ago (or so they say). My question is, is there a wary to test it for residual copper? and, is it worth thinking about for my reef tank at all? Thanks for your support.
