Popper's IM100ext part 2

Fleece rollers impact performance of skimmers negatively. However, this looks more like an air intake issue - I would check if it is clogged somewhere or air intake shut off.

Did you turn the magic red mushroom knob ?

Left it alone for a 2-4hrs. It is skimming foam now. No more micro bubbles.
