Everything moved to new tank, sand, rock, water, filters, lights, pumps and could add with additional 50 gal of fresh or could circulate the new water for days with the old tank water, can hold fish in small tank but not all corals. New sand would have to be added as the new tank has a bigger footprint.

My concern is its not trying to save a couple of bucks on sand, its cheap relative to the new DSA 140 tank, but to have all the bacteria that in the old tank to the new.
