A swing from high 70s to low 80's is not something to worry about.
My current tank hits 85 or 86 daily. Normally it would sit at 80

Man you're crazy

I agree with Brad.

My SPS tank hits 85 daily right now and has been fluctuating between 78 and 86 for the past 3 months without problem. In fact, with this recent hot-spell my SPS have looked slightly better than they have in the last month (but that could also be due to starting to add some amino acids so I won't suggest a causal link).

I was going crazy at first, but after a few weeks realized that nothing was stressed. Now I'm not suggesting tht this doesn't matter, because I certainly think stability is key, but my tank went the entire summer like this. This was also a heavily stocked SPS tank, and I would think would be the most susceptible to problems. Again, the only thing stressed was me.

Here is a pic taken that summer, as you can see, nothing bad was happening

SPS will survive better during higher temps as they come from higher parts of the reef and are even sometimes exposed directly to the baking sun. However for proper color and growth you'll want a stable temperature.

Lower light corals, most fish and crustaceans will not do well at such high temps.

Aquattro, have you checked your thermometer? 89 degress cooked my fish and shrimp!

Thanks for the input I guess in a nutshell Im not doing too bad and I wont worry about the swings.

Cheers

I think its important to mention here that a slow swing is what is important. I think the cooked tanks result from a tank going to normal temp to the high 80s or into the 90s within a few hours. I think the same summer Brad remarked that his was hitting the 90s mine was as well with no problems at all. Granted I didn't have any fabulous colors but everything was still alive. I think the temperatures were harder on me and I bought a chiller that year. When the chiller fuse blew that first time I lost a lot of stuff. Mostly because my tank went from a cool 78F to about 91 in the space of only a few hours.
