Temp was ranging a bit more then I would like. Sometimes it would be 78.4 -78.8 during the day and then drop to 77.7 to 78 at night. I thouhg cause of the heater being in chamber 2 the water falling into that chamber might cool off a bit more then the rest of the tank so the heater might be working more then it should. I did try adjusting it down a bit more before I moved it, but that did not help.

I placed it in chamber 3 and the temps are solid at 77.9-78 at night to 78.4 during the day. I have the nob between 79 and 75 on the heater and it seems to be holding temp better now that I have moved it.

You can also see how I have angled the pump into the corner so its not flat against that wall.
