I hit 92 for a couple of days last year and everything was fine. I put a fan on the sump and managed to get the tank down to a respectable temperature (88). This year even with the heat I'm managing an impressive 83. I also switched the pump on my skimmer from a mat 12 to a mag 9 which I think helped out alot.
What temperature does your tank get to at night??
