76 fall through spring
I try to keep it from going over 82 in the summer.

I put my tank in at 78. I would have picked 77 but my thermometer goes up by 2's

I use a small 50 watt heater in a 45 gallon tank. I prefer to use undersized heaters so if the thermostat fails the heater can't do much harm. So, my thermostat is set at about 79 F, but if it gets too cool at night the heater just keeps the temperature from dropping too far, and by the end of the day it is back at 79 degrees. On normal days and nights the little heater keeps the temperature pretty constant.

[QUOTE=Bert H;244856]Same here. In summer it's in the 80's. The heater (in-line Hydor) is set at 75 for those few Florida days where it will be colder.[/QUOT

Being that I am from Wisconsin that sounds hilarious. "set for 75 on colder days" A cold day around here is about 20 below zero
