 I am trying to figure out what you mean by adjusting the water level so it is 1/2 way up the neck under the collection cup.  How do you adjust this?  I thought the only adjustment on these skimmers was the air screw.  
I have been having a lot of trouble getting my Berlin skimmer to work properly and I recently ordered a new Kent Marine Venturi for it to try and increase the skimmate production.
