Protien Skimmers

[Myanth]

Is the water level in the sump really important for setting up a skimmer. I would imagine that it is due to pressure changes with water levels. The reason I ask is that I have a Red Sea Berlin that has needed constant maintenance since I set it up. I have downloaded the owners manual and it basically explains all of the "tweeking" necessary to effectively run one of these, but is seems like a real PITA. It skims lots but I always have to adjust water flow and air flow just to keep it going and keep it from flooding. Am I doing something wrong?

My remora is so nice in comparison. If I want wet skimmate I lower the cup, dry skimmate I raise it up. Simple.
