It's a remora hang-on skimmer. I already moved the cup level up. maybe move it up a little more..
BTW, having so much foams and bubbles in the skimmer's cup, does it indicate something is happening in the water?
I had tested run my skimmer on a fresh water tank before n I've never seen so much foam an bubbles in the cup. Is it because the salt in the water?
