Well I just got home from work tonight to find the tank at a whopping 85
I guess I should have setup the fan over the sump a few days ago. I had to pull out one of my first sps Milli's as it had pretty much bleached in only one day

I'm sad to see this piece go as it was doing so well with lot's of new small growth branches.
It's my fault though, I should have setup that freak'n fan yesterday
Lesson:
Don't put off until tomorrow- if you can do it yesterday!
