ok, sorry, i did look,and i appologize, that is why i asked, someone asked about using rock that they found in the alley behind their lfs, and i really did not like that idea(jsut the possible pollution, ya know)
anyhow, if it is dead live rock, FROM A REEF(not lava rock or somethign else), or just the ocean, then yes it will be fine, it may take some time, but it will become live again(and no one can say how long, all tanks are different, that depend on the h2o, the lr and the dead rockand the ratio and everything, lightin; and all conditions being equal, no 2 systems will be teh exact same), so just be patient with it, it will happen, and you can, yes,keep fish in the mean time, without problem, the only thing, you may have to battle the algae a bit, until the coraline takes off(but that can be dealt with, fairly easily)
