So my refugium and my skimmer are creating tons of bubbles. I have a mega flow 4 sump and the skimmer is in the first chamber and drains into the same chamber. Then there is a filter sponge that separates that chamber from the next. The second chamber holds my return pump which is tee'd into my refugium. The refugium drains back into the first chamber. I had it draining into the second chamber but the bubbles were so bad. I had to shut both the refugium and the skimmer off because the bubbles are so bad. Is there anything I can do to make my setup bubbleless??
