I wont tell
Just be sure to move over some filter media from your other tank to help seed it (you could put it in the empty filter tray you have)...Also you can get a pair of new cheap pantyhose and cut one of the toe parts out about 6-8 inches up and fill it with gravel from your other tank and hang it over the inside edge of your new one to help transfer some good bacteria over too(you could also put the gravel in one of the filter trays if you have room).....this keeps you from getting gravel mixed in with your sand and makes it easier to take out when done cycling.
