I installed a protein skimmer last week and I see the cyclone of water in the body of the skimmer but there is no foam accumulating at the top. Does anyone know how long before the foam and sludge are supposed to begin accumulating?
Also, there is a flimsy plastic tube hanging off of the thing with a tiny, twistable cap on it. I imagine turning it one way or the other does something but I tried it and noticed no difference.
I can't tell if the protein skimmer is set up properly or doing anything :( Any help would be appreciated!
