John, For your size tank it is pretty simple... Take the rock out and put it in a bucket or cooler with the tank water over it. Bag all the fish and coral you can remove (if you can not get the coral off the big rocks just be careful about stacking rock on it in the bucket or the cooler). Best advice is to remove the sand but IMHO it is not really needed for your small tank. Just keep about 1" of water over the sand. Move the tank carefully being sure to support it on the bottom at all times with two people. You have weight in the bottom and you do not want to leave it unsupported. Move it over to the new location ASAP. Place your rock back in, add about 1/2 of the old water back in. Add new salt water to fill the tank. If it has been a short move, less then about two hours, I would not worry about acclimating the fish. Done!
