Usable yes, but not fully developed hence the algae blooms, so with it not being fully finished I would cycle the other tank first for a few weeks atleast so that the new tank has atleast enough of a bio filter (be it algae or bacteria) to support itself and then put all the rock and sand from the 36 in there for a few days then the fish. of course the plan doesnt take into the amount/sensitivity of the livestock, size of upgraded tank etc
