120 gal with 54 gal sump on mainfloor???

If the tank is on a load bearing wall then it should be perpendicular to the joists which is good. All together you're probably looking at about 2000lbs of dead weight which isn't that much provided the room with the tank is larger than 100 sqft and doesn't contain other aquariums.
