Yes.. Exactly.. Here is the article..

Its 1/10th the bacterial population in the water column not total bacterial populations.. To say that skimming removes 90% of the bacteria in a tank is incorrect. It can remove ~90% of the water in the water column only.
Far higher bacterial counts are present on surfaces of the tank than are removed via skimming.

And a quote from the article..
Of course, bacteria export by skimming requires that the bacteria actually reside in the water column and not as a film on a solid support

Who me?
