Water temp variance

[Reef Pilot]

I didn't get a response to my first post on this subject. Am hoping that there is enough experience in these forums to tell me if this OK.

My inclination is that a 2 or 3 F temp variance should not affect the fish. I still remember snorkeling in Maui last year, and encountering cooler and warmer currents at times in the same reef area. So if I can feel that difference, it must be at least a couple degrees F variance.

I've read that any 2 celcius is about the most you want to change day to night for a stress free tank. I have about 5 farenheit day to night, so a little over, but happy fish, so no worries.
