I am having a hard time finding a lot of information regarding fine tuning these skimmers. Currently I am having issues raising the level in the skimmer body high enough to skim. The three adjustment methods do not seem to make much of a difference. I was able to finally get it to raise to the bottom of the cup but I had to almost entirely close the main adjustment tube which I am sure throttles performance (since that controls how much water is released back into the sump from the skimmer). Anybody else using these skimmers?
, and it seems to have fixed the issue. The controls adjust properly and the water level is where it is supposed to be.
