Temperature questions?

[canadawest]

My temp is 80 at night, with a peak of 83-84 by late evening at the end of the MH photoperiod.

I do intend to get some fans installed in my canopy before the summer temps begin in order to avoid ugly temperature swings, and to hopefully maintain the overall swing from 80 low to 82 high.

I also tend to agree with Borneman and other's articles about average reef temps being in the low-mid 80s, and with overall global warming increasing that trend I think we're going to see future generations of species having to adapt to the higher avg temps.
