    depends on the rock

    Most rocks u could use i guess but the favoured rocks are those made up of calcium carbonate or aragonite as they dissolve to a very small extent and realease calcium making it easier for coralline algae to grow ect.

    Hi Gershwin - MOST rock you collect around the Cape Town beaches, are created by some LAVA and is far too solid to make any decent live rock.

    IF the rock you are talking about, is extremely porious, and very light, then YES - leaving this rock together with some actual live rock, would have the critters and bacteria populate this "dead" rock, and then the "dead rock" would become "alive".... it will most likely NEVER be as good as the "the real thing". But, it can become "usuable", I think. IF you get/use the correct rock with the correct characteristics!
