Ok have the G2 in sump doing it's thing ,followed instruction from the asm web site water colum is about 1 inch below collection cup. and the riser tube is as high as it can go, the whole skimmer unit is in 10 inchs of water.

#1 So Does the skim or foam rise or bubbles float/flow over into the collection cup or does the water push it over ??

#2 what does the adjustable part on the pump that the venturi is connected to do?? on the pump (it turns left & right, does it adjust flow?)

thanks for the input still trying to figure it out.
