I personally would go to the lfs and get crushed coral or a few chunks of coral, or maybe even some non-coated sea shells ( snails, clams, etc), rather than try to clean up some deceased live rock of my own.

I don't see a problem with your rock as long as you sanitize it well and add it slowly so you don't shock your fish by uppping the pH and hardness too quickly for them to handle.

If it's a calcite-based rock, and it's been sufficiently cleaned and sterilized then go for it. I don't see why it could hurt. To see if it'll raise pH though, drop some vinegar on the rock and watch for fizzing. If it fizzes, it'll help raise your pH. Or you could just get yourself some limestone, travertine, or tufa (there's others as well).

With live rock in what you are asking about, there is many small holes that contain benificial bacteria. There are also many small animals and such that live in these. Even if you were to sterilize it, you would not be able to get everything out. This would be die off and would pollute the water. I personally would not do this. Also live rock can be spendy, why not go with cheaper rock?
