is it possible? just picked up some rock. it was given for free, about 60 pounds. it was moist and in garbage bags. no smell to it, a little green algae on it, not sure if it was live or not? brought it home and tossed in in my 55 thats running with only 1 yellow tang and a conty and already established live rock and sand. did i do the right thing? if its dead will it come back to life? how long?
