I suppose your tank is pretty heavy. When your new location is perfectly ready I would empty your tank water into 5 gal buckets, I am assuming these to be clean and (fish ok), Put any live rock etc into them, when enough weight is removed and your tank can be moved without racking it move it first, immediately pour back the 5 gal buckets, etc. Try not to loose to much heat or slosh. Good Luck! I guess you know water it 8.33 pounds per gal.
