Temperature and Marine Aquarium

What is the right temperature in aquarium? In our vision it has to be the same of the sea. But in the last years this assumption is not so valid. Our researches have found out that in the coral's sea we have an average temperature between 26 to 28 C degrees. With minimum of 21 and maximum of 30. Anyway corals can adapt themselves to high temperature, but they need time, so we can have 29C in the summer if we have 27 during all year long. As the increasing of electric bill, in the winter we have to adapt our temperature to less degrees, so 29 is not an option now. We suggest to follow the Nature, so dont go over 28 if you can.
But, just to speak, whats happen when the temperature rise up? The content of oxygen goes down, and this is a problem for every living being. But the methabolism rises up, and this brings more active fish and more beautiful colors. The strange is more methabolism needs more oxygen so it can be a nightmare, more demand but less oxygen in the water. So if the temperature rises up too much, the animals begin to suffer. What do you think? What are your strategies about? What's is your preferred temperature?

I have my main system on a seasonal cycle with 24 the lowest in the winter and 27 the highest in the summer. This is for once to simulate the natural seasonal changes, but also to save some energy.

As for what extreme temperatures fish and inverts can handle - I've seen shallow tide pools on the North Sea cost that were blasted by the sun and outright hot (30 C wouldn't be surprising), yet the fish and shrimp in there didn't show the slightest inconvenience. Mind that these were temperate-cold species.
I think the temperature alone is not always the issue but rather the oxygen depletion it may cause. Though if there is enough surface area to ensure a sufficient gas exchange, the animals may very well hande temperatures well above their comfort level.

BTW, I also have a Sea of Cortez/Tropical East Pacific tank, and that one I pretty much keep at room temperature. Especially the Sea of Cortez has very defined seasons with temperatures going as high as 30 C at the end of summer, and as low as 16 C at the end of winter. It in this regard even more extreme than the most of the Mediterranean Sea.
