When I came home today, I found all the corals a little happier. The toadstool looked a lot better. And, this is even though the temperature was 82F. To lower the temperature, I turned off all pumps (except the ones that break the water surface), turned off the lights and turned the fans on high.
I am still not in the clear, though, since the AC was not turned on today. My dog didn't look too happy today either when I got home, so I took him to a friend's house where he can stay until the AC is turned on again.
Thanks all for the input.
