First i made all fresh saltwater in the new tank. Got my sump filters and heater running. Transfered live rock to one side of tank. Used clean/new dust pan and took the sand out of the old tank, added new live sand to cover larger tank. Tried to aquascape and gave up. Let run for 2 days added old fish and inverts. Asked around a lot about cycling, because I had live sand and rock from old tank I didn't need to wait before adding livestock. Even my tang did well with the transfer.
