I got the Bubble Magus nac5e from Brad and Dave at concept. Great skimmer and does not require any adjustment except for the air and water valve. As Brett says, "that's one big skimmer".
My only complaint is that it is hard to clean. You need small hands to reach inside the chamber and yet still, you can barely maneuver a cleaning brush around. Also, Bubble Magus uses metric pvc so if you want to extend any of the pipping, you can only buy from online sources.
It did overflow on me though. The first time was because I did not have an ATO and the water level in the sump dropped too much. That raised the water level in the skimmer and overflowed. I now use the drain plug going into a milk jug down below. I said first because it's bound to happen again at some point.
As you can tell, it's a site for sore eyes and is as tall as a 5 gallon bucket. It's going on my 90 gallon and into the sump when my basement reno is finished.
