i have personally moved my 75 reef twice and was very successful......your best bet is to remove like corals and place them in rubbermaid tubs with some water from your main tank syphoned off the top. then gather all the rock carefully and place them in a separate tub as well. gather all your critters and place them in another tub to keep them from getting crushed by the rock. it is worth your while to clean the algae off the front and side glass while you have the tank empty. LEAVE YOUR SAND IN THE MAIN TANK AND TRY NOT TO DISTURB IT!!!!! cover the tank and if you have a truck or a moving truck that is great. make sure you keep the temp good in your tubs----mainly the fish, corals, and inverts. if you devote a whole morning to this, you can get to your destination and put some plates, or paper plates on the sand and slowly start filling the tank back up. (the plates keep the sand from getting too stirred up.......once you get several inches of water, you can start putting rock back in. while you pull the rock from the tub, shake off the sediment and let it settle before getting water from that tub to put back in the tank....... set up your filters and powerheads and put your critters back in if the temp is right.....the sooner you can hook up some filtration, the better......remember, in the wild, funny things happen and all conditions are not always perfect!!! if you are careful and take your time, you will be pleased with how healthy and CLEAN everything will look the next day.....hope that helps, you shouldnt have a problem!
