The tank and other equipment probably will be fine with a cleaning with some vinegar. If you are very worried, wiping with a dilute bleach solution would be safe enough for the tank. I'd work outdoors to reduce fume exposure.

For the corals, a dip like Lugol's or one of the commercial products might do the job. I'm not sure about that. A freshwater dip for the fish should be enough, with some luck.
