To further clarify , when the skimming occurs 90% rides the bubble train in to skimmer cup town , the other 10% builds up in the cups neck , after several days so much builds up it effects the effectiveness of the skimmer , so I have to clean the neck although my cup isn't even half full , then it takes a day to re break in , so by knocking the heaviest of the crud off to be RE SKIMMED I keep my skimmer running at an optimal rate .
The gunk doesn't go in to the sump or tank , just blasted apart by the pump and bubbles .
I made up those percentages , honestly idk how much is actually pushed out opposed to the amount sticking to the neck
