I just wanted to share my experience of swapping out my 75G tank with my 90G just acquired from BostonEric! Thanks ERIC!! 
Late Sunday afternoon I drove into my driveway and had no one to help me move the tank out of my truck! I'm French, so I did this myself... Belive it or not, I was actually able to lift the tank solo and move it in for the night.
Monday, after a few calls, I drove out to my LFS and grabbed UGF plate (48x13) and powerhead (Aquaclear 70?), so it is not full size, but I didn't want it to be. I got home at 1:30pm.
I next put the 90G back into the truck and backed it up to the front door. Using my planks again, I slowly slid it down onto a waiting rug and used this to slide it into the next room. Rinse and repeat for the 35 and 45G rubbermaid barrels of gravel and Eric's old tank water.
2:00 - Started draining the 75G. I had all of the accessories and everything set up waiting to go.
2:30 - All of the decorations and plants were removed and out of the way. the remaining water in the tank is being syphoned into the 3rd 35G riubber barrel double-lined w/ 20G fish bags (from the LFS). After placing an old air-pump in there I waited for the water to fill.
2:45 - Fish have been removed safely (BTW - The Raphael DOES talk!!!).
3:00 - Next I proceeded to 'slide' the 75G off of the stand and onto another (see image). I also next lifted the 90G and did the same. Before placing the 90G onto the stand I added 3/4" plywood to increase support and strength to my existing stand.
3:30 - Finished placing the 90G into place and removing the 75G as well as filling the tank with sand and gravel (Used the gravel provided by Eric, which was left in his old tank water)
4:30 - Tank is finished filling, major items are added and both filters (powerhead and Penguin 400) have been up and running for ~20 minutes. Fish have been doing well. Letting the water settle before added them.
5:00 - tested the water: Ammonia/nitrItes = 0.0 NitrAtes = 0.05
5:30 - Fish added and clean-up begins... Leaving lights off and letting fish 'chill out'. Orange water is from the driftwood, which was only a week old when in the 75G.
*Fish were in the barrel for 2.5 hours...
6:00 - Added a nylon stocking full of old gravel from 75G (about 2 lbs). Tested the water: Ammonia/nitrItes = 0.0 NitrAtes = 0.10
Tuesday 6:30am - Tested the water: Ammonia/nitrItes = 0.0 NitrAtes = 0.10 (myabe 0.15ppm)
Last Piucture was taken at 5:45 pm Monday
