The only issue I'd be concerned about is killing off some sponge and causing a cycle. The corals can be exposed for quite a while.
I agree, large sponges need to be kept submerged but most corals do for out of water for several hours as long as they are kept warm.
Don't forget about glass or Boron heaters, they cannot be on while dry.
