Wow, Mr. Wilson goes into great detail about the rationale for how you should decide on an optimal temperature for your tank and Shimek's research. I only read the Shimek article. Great add on Mr. Wilson, you can google his link as he has a lot more discussions as well about other reef topics.
Niko, I would look specifically on what temperature you should keep your tank. I think you said your tank is newer?
Reason being is I don't want everyone to just take this information as a blanket statement that everyone needs to put their tank at 82 degrees.
I do it for my SPS, I do it because I have an oversized skimmer that adequately aerates the water, I do it because even though it encourages green algae growth, I have biopellets and tangs that keep it at bay, I do it because average temperature in the room is 78 degrees, I do it because I have 3 metal halides with a small clip-on fan on the side and an auto topoff system to compensate for the evaporation, I do it because I have my own do/ri water to easily refill my topoff.
If I mainly had softies or LPS, I would not run the higher temperature, no point in my mind and all that risk of overheating for nothing. I wouldn't run it if I don't have the eye for seeing changes in my coral and knowing immediately that there is something wrong, or that my tank is not mature yet (at least 1 year in my opinion). If I didn't have an oversized skimmer, I would not run the higher temperatures... I hope you get my drift. Each tank and application is different. Sorry, not singling you out but I just want to make sure everyone is not jumping on the bandwagon without fully thinking about their own system charcteristics and the need for it or not. Plus, why expend the extra money on heating your tank during the year for no benefit if zoas or LPS are happy with 78? Just my 2 cents.
