I recently moved and due to an injury decided not to set my 75 gallon saltwater tank back up in the new apartment. I donated the fish and corals to my local fish store and left the 100+ lbs of live rock in 5 gallon uncovered buckets of salt water sitting in my unheated garage for the past 6 weeks. Well, now that I am feeling better, I want to set up my tank again. Question is what do I do with the rock? Is it saveable? Cleanable? Reusable? Any input would be greatly appreciated!
