Hi Blob,
Looks like your skimmer is happy in its new home!
I have my air setting on max, but inserted the additional silicone tube onto the the airvalve nipple.
Also I have the "tiny" bubble height adjusted so that it is level with the bottom of the collection cup.
With the water level staying consitent i(about 7.5 inches) in my sump, I usually have about 1/2 cup of skimmate after a week.
I think everyone is different in how they like to adjust their skimmers, but this seems to work for me.
