Copper and LiveRock

[margaritaville]

I have treated my fowlr tank with coppersafe and am wondering once liverock has been in a tank with copper is it now bad forever. Or can I use some of it in setting up my reef tank? Thanks for all the help

I would not recommend the use of any live rock in a reef that has been exposed to copper. just my two cents worth.
