I do not have one but generally it would be a couple inches below the last baffle.

Hi @xrayreefer
I have the IM 40. And unfortunately the documents do not really detail how the water is supposed to flow through the sump area. However, the picture above does a fairly good job of describing where the water level should be in the middle (return pump) section. Basically the water cascades from the outer sections to the inner sections.

In my IM40, I generally keep the water level in the return pump section (middle) between 1 and 3 inches below the baffle.

Hope this helps!
