Well Gary it looks like you and I need to get together and take a trip to Fiji for a year and study tidal pools...lol.
I don't subscribe to this theory at all.Most of the corals we keep will do perfectly fine at 84. It really depends on what they are used to though. If you keep your tank at 78 and don't let it fluctuate, the corals will be used to that temperature. Even if you tank gets up to 83, it could be trouble. If your tank is used to fluctuating between 78 and 81 or 82, a jump to 84 or even 85 probably won't even phase your corals.

Many Acans aren't going to be happy at 84-85 no matter what.
finally got a digital thermometer, found that my tank fluctuates between 79.2 and 85.3 already!
I need to figure out a cheap way to cool the tank until I get the bigger setup.
I'm not advocating a constant 84 for most reefs. I asked that question on MarineDepot specifically for BTA. But letting your tank hit 80 isn't going to hurt a tropical reef tank. Lots of people spend lots of money trying to avoid 80 degree water. IMO, there is no need.
Would the picture you linked look any different if the dates recorded were in the Southern Hemisphere's Summer? Say January? How different is the water temperature on the Great Barrier Reef?
why not? IME they do fine.What about the SPS that can't get enough light if you blast them with 400W MH? They're used to the extremely high temperatures of being so close to the water surface. They won't be happy at 78 will they?[/url]
