i just moved a 100 gallon fully stock reef. i would get some 5 gallon water jugs and try to save at least 75% of the water if possible. i bagged all live stock (corals and fishes) in separate bags and put them in styrofoam coolers. (if you are transporting in something where the temp may drop dramatically, do use the heat packs.) i put the snails and hermit in a couple of bags together. i put all the live rock in styrofoam coolers and topped with news paper and soaked the news paper with water from the tank to keep the rock damp. and most importantly if you can move the tank without disturbing the sand bed you should. mixing up the sand bed can release massive amounts of nitrates and ammonia. if this is not possible the sand may have to be replaced. im sure one of the experts could tell you more about the sand. i did all these things, and immediatly set the tank back up and put 25% new saltwater, aged one week, in the tank. thankfully i only lost one fish. good luck, its tough, but you can do it with careful planning.
