Best temperature for reef tank

I have my tank set at 79F and that's what I've heard is best for a reef. Is this correct??

 

anywhere between 76-81 is ideal

 

Mines set to 79-80 degrees F

 

Mine is set to 78-79, but it's been running at 74 to 76 thanks to a relatively cold winter so far and my heaters' lack of ability to keep up.

 

Alright thanks guys.

 

I used to run at 80, but now i run at 76 bc cost of heating is less, and the water evaporation rate is lower.

I've seen people run beautiful reef systems as low as 72-74.

 

78 here.

 

I try for 78-80

 

I run all at 80-82, I like to keep them a bit higher year round as our summers here are hot and the house doesn't always stay at 76-78 and I do not want to use chillers.

 

i try for 78 but mine stays at about 79
