Is the liverock really garbage now? because in my system I had enough free copper to kill half of my corals and the rest was in shock for a while but I had my water tested after a month and no more trace of copper. From my experience the copper will not be absorbed so much into the liverock and will eventually bind to organic matter and be neutralized or at least turned into a non toxic form and removed by the skimmer and syphoning of the sand.

I did not change my liverock after the copper poisoning and everything is thriving again in my tank. Copper is at very low level so normal level for saltwater, so my liverock is not leaching any copper or at least not something that can do any level of dammage, and I have a very porous Totoka liverock.

I would test for copper before throwing out good live liverock. I am guessing that with Cuprisorb and a few good water change, the liverock is going to be perfectly fine.
