here is a link to a thread where i put some info in on this topic. there should be a link to a RC thread that discusses this in depth.
i have cooked some rock and am really happy with the results. there are still critters alive, including some aiptasia that i have been killing with joe's juice. i continuously find pods,
brittle stars, stars, etc in the rock too. i wouldn't recommend cooking a rock covered with your favorite coral without at least fragging it for safe keeping, if not removing the coral entirely. not worth the chance.
