So I upgraded my glass sump to a new acrylic one. When I turned everything on, my skimmer went crazy pushing bubbles out. I've ran this skimmer for a year it's an sc aquarium brand. The water level is same or a tiny bit lower that the previous sump. If I raise the skimmer nothing changes and it spews bubbles like mad still. Is this normal when switching from glass to acrylic? Nothing I do seems to slow it down
