Bubble Magus180-CS Cone Skimmer

[born]

Hey I purchased this skimmer, and it was working fine the first time I had it going, but then my sump cracked and had to replace the first sump with a way higher new sump tank. The skimmers suppose to sit in 9.5-11" of water. The baffles are about 13" inch so what I did was place the skimmer on some pegs that are about 2". So the skimmer is sitting at about 10.5-10 3/4". But the skimmer just keeps bubbling over and over and filling up the cup with water and mass amounts of bubbles within seconds. Ive tried toggling the little gauge down on the pipe (MAX, 5,4,3,2,1). But no matter what its on it will just keep flowing over.
Anyone have any ideas?
Maybe its still in too much water and I need a higher stand for it?

My first sump it was sitting in I believe 10"-10.5" and was working wonders.
