    Anything that has been in a saltwater tank will become live. All live means is that it has a population of bacteria living on it that can process fish wastes to less toxic chemicals. That is how you can make live rock from dead, dry rock.

    Live rock will tend to be more colorful -- it will have greens and reds on it. It will smell like the ocean, too. It may also have sponges growing on it.

    Smell! Dead rock smells bad. Coralline is good indicator of live rock.

    You can take a piece of rock with it on it and scrape it off into the water. There is also a product called purple up that a few people have use ( i havent)
