I agree with Myka on the coraline, I just pulled about 40 lbs of LR out of a tupperware container that I had it all in with the lid on for about a month while I worked my new display tank in.
The coraline was all gone, there was still a little aiptasia which had all turned clear and a few fanworms still kickin it and I have also seen some bristle worms as well, there was still some macro algea intact as well,though it looked like it was on it's last legs.
I thoroughly swished this LR in a fresh bucket of SW piece by piece right before putting it in the tank and was amazed at the amount of crap that came out when I did this, the water also smelled like a sewer once it was all said and done too.
I'm pretty sure that all the detrius that came out of the rocks is much better off down the drain than in my tank.
I hope.
