I am getting 110 lbs of live rock on Friday, (ordered online). My tank is not set up yet so it will be going into a 35 gal container for now. The guy said I should have it saltwater (obviously), a circulator, heater and light till my tank is ready to fill. I too am afraid of what lurks in the live rock, so, before I put it in the new tank, I should put it in FW for a while to kill any animals that might lurk in it? But will still retain the good bacteria?
