The issue is your baffle heights. The way it is the water is going to fluctuate its level because its higher than the low baffle on the return chamber. Without an ATO, or ato failures... the water level in the skimmer change is going to change whereas the level should only change in the return chamber

And if the level does change its going to mess with your skimmer setting.

I would take water out until the return chamber drops slightly below the level of the rest of the sump. That forces your return pump to drive the overflow and maintain your sump at a consistent level. That baffle looks pretty low though..so ymmv. Maybe try and raise the height with a piece of acrylic and add some teeth too.. I'll post a pic of mine later. Which model sump is that? I have the R100.
