Dead Live Rock

[ChefFish]

So, like most people I assume, when I first went from FW to SW there were a lot of things I didn't know and I learned some hard lessons,lol. I have around 100lbs of live rock that has been in buckets outside for the last few months. I had Aiptasia problems among other things. Is there a way to make the rock safe to use as base rock? Is there anyway of bring it back to "life"? There are some nice pieces and I would hate to see it go to waste. at the same time, I don't want to ruin my water quality or deal with aiptasia again. Any advice is appreciated!
