| Through a controller my heaters are set for 78 degrees all year around. Also have a chiller set for 80 degrees all year around and have not had any problems. I live in Dallas where it often goes over 100 degrees during the summer months. This is on our 200 gal reef tank. By the way the lights even cause the chiller to kick in even during the winter on warmer days.
I would just set at 78 and leave it.
