Where do you have tank temp at?

[Chowder]

I keep mine at alow of 78 to a high of 81. My heater keeps it above 77 and chiller keeps it under 81. I have some heat issues in my tank and when lights are on I don't need a heater in winter , it just keeps it from going to low at night. In summer don"t have to use a heater just the chiller and AC in the room.
