I will say first I am still learning the saltwater world however on the question about moving the tank......I would first siphon as much water out of the tank that you can. Then lift the stand tobthe 2x4s....then put the water back. Doing this shouldnt be a problem...howevetbdoing this full could be detrimental to your cause as the glass gets weaker when not used as intended. I dpeak from experiance in that manner.
