I tore down my 55g 4 years ago when I moved out of state and got hitched. I have about ~60 lbs of fiji rock that was just taken out of the tank and kept in buckets (all dried up). I didn't think it would take this long to rebuild the system (other priorities) but I'm in the process of building a 75 g reef tank and using my old 55g to build the sump. The advise I got from quite a few members here on RB is to just cycle the old dried up rock with the new rock I'm buying (an additional ~50 - 60 lbs). I never cleaned out my rock but now that it's dried it's all white. I took it out of my shed last wknd, left it on the deck and it rained, now I could see specs of purple algae growing (possibly coraline?). If you're planning on setting up the tank in the near future, I wouldn't dry out the rock...everything on it will die, then it's no longer live rock. Keep it in some sort of rubbermaid tub with a few powerheads, a heater and possibly your skimmer...if it will be a while before you setup the tank and you have to dry it out I think you could just put it out in the sun, just keep in mind it will just be like base rock when you do decide to use it again, but if you add some new live rock/live sand, over time the old rock should be live again.
