In the picture it looks like the 2 1" drain lines join at a tee and then go into the skimmer tub. This will reduce the drain capacity to that of a single 1" line. I don't know how much you want to fiddle with it but could you have one drain line go directly into the skimmer tub and then have the other drain line go directly into the first chamber of the glass sump? I think this would help with the fluctuating return section.
