Night time to daytime temps on a reef can vary as much as 5 degrees on average. Current changes call also make very dramatic changes throughout the day. Lastly, when you consider seasonal swings the temperature on an average Indo-Pacific reef can range from 75-90 degrees.
Here's just one of many references that dispell that age old myth that things like temperature are stable on coral reefs.

That said I'm not supporting people try to have big temp swings in their aquariums. However, the nonsense about how important it is to keep temps perfectly stable day in and day out are nonsense. I've even seen suggestions that temperature swings aren't only normal, they're beneficial.
