has anyone ever used this in there tank? If so I would like to know how to get rid of it. My wife poured about a third of the bottle into my tank and I was doing some research on how this stuff binds to the rocks and the sand. Is there a way to get rid of the copper in my tank even though some say that copper power is not really copper or should I just buy new rocks and sand? I would like to put corals and possibly a clam in my tank and invertebrates but I can't if there is any trace of copper. Please let me know. thanks in advance
