Be careful, I tried moving a 300 reef to a new house and lost everyhthing. I basically move the entire reef into large 50 gallon rubbermade trash cans, connected my sump and all the filters... and had it running OK. Moved the tank, filled with salt water. The next day was supposed to be move the livestock to the new house, (only 10 minutes away) came home from work and everything was dead...one of the heatesr went bad and electrocuted everyhting.
I was so sick over this, I sold everything, all my tanks equipment...that was 12 years ago, now iI'm getting back into it again but with fresh water only for now.
