68 to 76 degrees, although it has gone lower. My main concern is that it gets no warmer than 76 degrees -- so, considering the house isn't airconditioned, sometimes there is so much condensation on the tank you can't even see inside.
77.5 - 80 The Neptune Controller lets the heaters and fans duke it out.
I will need a chiller come spring though...
Both. I shoot for natural reef temps, which means a low of 76, a high of 86, and an average of about 82.For the people that run 82+ is that by choice or dependent on the room temp. I guess what I'm asking is that are you purposefully varying the temperature in the tank?
