i have moved a few tanks and have always just draned all the water then scooped out the sand with a fish net. This way all the nasty stuff that is in the sand stayes in the tank. Just try and make a few buckets of the sand and put in the firts sand out back in last. Now my tanks were never as big as a 110 i had a 55 and a 28 reef . All and all things were a lil stressed but everything seames to rebound just fine.

Im waiting to start my new 54 gal corner and everything from my 28 will be going in when i start it sand and all but i will put the old sand on the bottom and get some new sand on top.
