Curing "live rock" that was in fresh water
I have just acquired a 8gal BioCube from a buddy. He used to have it as salt but has been running it as freshwater. I took it and added saltwater to it, and have it running. What do I need to do to get the rock to be live again. it is in there in heated flowing water. What do I need to do to cure the rock?
Thanks for the help.
