well, i'm finally starting my reef-tank, a sixty gallon and i have a dilema. my friend who broke his tank down about a month ago, game me an ice-chest full of his live rocks from the tank. the problem is, he let it sit in the ice-chest w/o water all this time. my question is, is it safe to use? should i do any kind of cleaning? if i wash it in fresh water, wouldn't it kill all the bacteria(if they are not all dead already)? he has some AMAZING pieces and i would love to use them. help me out, please. i know you guys always do, so thanks in advance.
