OK, for the last 2 days, I have been running the tank 0 lights. Just the 2 External pumps. No heaters either, and it's STILL running 80* Checked the thermo in my other tank, within a degree. Unplug the Little Giant 4 and temp drops to 79 after a few hrs.
Just WOW, there's no real head restriction in both pumps, and no water to motor contact. They are both external pumps, air cooled. But yet they ARE adding alot of heat. I'm baffled how that much heat can be entering the tank. House is kept 70/day 65/night
