I have several SPS tanks. Back in "another life" I had added things like mushrooms, palys, and GSP. Now these things have become invasive and are encroaching on the SPS. In addition, I have several Montiporas that are getting out of hand. I want to go through the rock and take out any that are "contaminated" and replace them with "virgin" liverock. My question is: Is there any process/procedure that I can perform on the affected rock to purge it of the troublemakers or do I actually need to get it "out and away" and replace it?
