Both Dr Ron Shimek and Eric Borneman advocated running reef tanks at relatively high reef temperatures (27-29C). To quote Borneman (ref: Aquarium Corals, pp 348): "
Although it has been recommended in the past that aquarium temperatures should be maintained between 24-27C (75-80F), the natural temperature of many Indo-Pacific reefs, especially in the shallow areas where most corals are collected, is higher than 27C (80F). Recent trends favour maintaining somewhat more natural reef temperatures of 27-29C (80-84F). The reasoning behind this increase is that the entire metabolism of the tank is raised , including those of the microbial community, detritus processing organisms, and herbivores. Furthermore, it is a more natural temperature for many reef animals. The increased rates of calcification at these temperatures should, therefore, not be offset by increasing algae growth, unless the system is mismanaged".
The underlined section above has motivated me to try relatively high reef temperature in my own reef tank.
Note that there are opposing views as well which should be noted (
