How hot is too hot?

[Sophie10]

82 nights, 84 days and holding. Using reduced lighting, freezer packs (safe), AC unit and fans. Crisis should pass now, a cold front, low 80's, Yay! ANd yes, I was one of the poor slobs working outside all week. Actually as 100 degree days go, Thursday wasn't so bad, there was a steady breeze to help!
Stay cool all, hope tanks all pull through...

Geez Dave, why are you playing outside all the time? Looks like you were on top of the temperature issue. Hopefully you can get that down. What was the ambient temperature in the room the tank is in?
