New chiller setting

[Ltjessec]

Hi,

I recently moved to a much bigger place. In my previous place I was able to keep the temperature in the apartment at at 72 degrees. This kept my nano at a temp of about 77-78. Since moving I cannot keep my house at 72 because the power bill would be cost prohibitive. The temp of the nano would rise to 82-83 degrees. I decided to get a chiller. I repurposed a water cooler to act as a chiller. It works well. I have set it up so the chiller kicks on at 78.5 and off at 77.5. Attached is a temp graph of my tank. My question, is the temp fluctuation ok? Should I set the temperature range to something else?

Thanks,

Jesse

Here's mine. It's a JBJ 1/10 hp on a 75 gallon, and we keep the house at 78°
