[Doug]

78 to 79 for me

77.5 is where mine sits. Never moves more than half a degree

[ReEf BoSs]

78-80 for me . Never try to go lower than 78 or more than 80( summer) anymore . Except when i went on vacation and it went to 95 .

80 all year long
since we all live in Canada :-) 26.6c

I run my tank cooler at 76, worked for me...but I guess between 76-78 will be good if you don't run a chiller so there is a buffer if ambient temperature gets too high.

I voted for 78. My system generally runs anywhere between 76-80 depending on the time of day and the season, etc.

My old SPS reef used to sit 82-84 and my current mixed reef sits at 78-79 and I see no real difference. I do think the slight temperature difference changes the metabolism of everything in the tank though, so I find tanks are easier to maintain when they are kept under 80.

I run my tank between 75-76 frag tank 74 and seahorse tank 74.
