Hi There, I finally ordered a protein skimmer. I just installed it (AquaticLife Internal Mini Protein Skimmer 115) in my sump. I think I have it set at the right water level. My question is about the air intake flow. I had it set too much and it quickly bubbled up and filled the cup with water. Right now I have it bubbling about 1/3 way up the cone. The manual wasn't very clear with where to leave it. Do I leave it where I have it, and as it skims it eventually gets thicker and up and over into the cup? Help please.
