My tank is considerably smaller than yours, but this setup keeps my tank at 80 at night and 82 during the day. I would like to keep it under 80, but if I set my heater to 78 the temperature will fall to 78 at night, but still go up to 82 during the day, so i keep the swing smaller by setting the heater a tad higher.

The way I see it, using a temperature controller to control a fan is a waste of money. You know the tank will get warm when the lights come on, so why not put the fan on the same timer the lights are on? Also, the fan will not likely cool the tank too much, and if it does your heater will take up little electricity.

This will not work on my tank as the light's are on 4 different timer's and I have not run a heater on this tank AT ALL since it has been up and running. With all the pump's for return, closed loop, 2 skimmers with feed pump's and a pump for my NP pellet's my temp never got below 78 or above 81 until the summer heat and the AC in my house does not affect the room the tank is in as much as the rest of the house.
