[Chaloupa]

we just did our 120g...we have a stock tank(horses normally drink out of these) for water change water that we emptied, transferred all live rock, fish and corals into, which then allowed us to keep a good portion of water (100g tank), put in a heater, powerheads and a lid and started work on getting the new 120 into position to plumb and hook up the new pump, and water test it. All in all it was a 24 hour adventure that went off without a hitch. Once we had water tested it after plumbing the new pump, we cleaned it out again and started to wash the sand. I had many concerns over the sandbed as it was 1.5 years old and I had read too many horror stories about moving established sand beds and wanted to start with a "fresh" sandbed seaded with a portion of the old sandbed. We got the sand in with some of the "old" water, and started to put in rock and fresh SW to top it up. It was easy...the only thing I have had is a small algae bloom...other than that you wouldn't even have known...except the new tank has no scratches and a black background!
