I recently setup my DOS to do a daily AWC (1 gallon), and notice my sump level going up after it's finished. I went through the whole calibration process...and both sides tested at 40ml. I've primed both lines and don't see any air bubbles. Is there a way to manually edit how long each side runs? I thought maybe it was because of slight variations in how long the lines were (the DOS is much closer to the new salt water container than the sump)....but the calibration seemed to debunk that. Anything else I should check?
