I've got a four foot vertical fan in the closet, going at the back of the tank. (There's a few feet on either side of the tank) It's lifted on a shelf so that the cool(er) air is covering the height of the tank and canopy. The air is actually cooler back there now than it is in the room, since all that heat is being pushed out here.
The tank is 80 right now. I'll be picking up another vertical fan to oscillate around the room and into the tank's area. I just hate going to wal-mart. It may take a while to get around to adding the extra AC vent, but I'm hoping that will drop it another few degrees.
