What you can do is a few things. First off you can seal the tank in plastic wrap with an air line and pump feeding it from outside. I have done this when bombing for fleas a few years ago. I would also recommend turning off your protein skimmer so you do not inject any air from the inside. Keep the lights off to prevent heat build up. Turn off any pumps for flow to keep heat build up to a minimum also. Maybe one power head pointed at the surface for a bit of flow and oxygen exchange. That's all I can think of right now. You should be good to go.
