I'm upgrading my Evo 13.5 to an Cube 20. My plan was to use new live sand as I've heard horror stories with switching sand over, use some existing rock and a few new pieces and then siphon all the existing water from the Evo over and then top off with fresh saltwater. I plan on letting it settle and then acclimating the fish to the new setup as there will be 1/3 of the tank of new water. My fear is that it will be a huge shock to fish and coral even though the majority is what they came out of.
