Temperature Swings

It’s that time of the year when it’s too mild outside to leave on the AC. but it’s still too warm to leave the windows open and ceiling fan on without having your tank temp rise.

With that being said, what’s an acceptable temp swing without stressing out your corals and other inhabitants? My tank has been fluctuating between 77-80 this past week and it’s driving me nuts. I don’t want to lose it hurt anything due to these temp swings.
Thanks

I try to stay with 1 degree swing either way. My temp controller is set at 80 and low temp set at 79, high temp 81. If it falls above or below the controller alarms.
