Greg when you refill your reservoir is the highest point higher or lower than where the export drains?

If its lower your back siphoning your reservoir into the main tank, lift the tubing up a bit and it should fix your problem.

That being said I have used the Tunze ATO for 6 years now, has worked flawlessly for me the whole time and I have not been nice to it (dry pump left right and center).
