Anyone Have an SRO-2000int, Advice?

[Tetrarch]

I originally ran the skimmer at 8" but it just kept overflowing, then I read around on the web and found that most people had success running it in the 5"-6.5" range, and that any higher usually resulted in a very wet skim/overflowing. Now I've dropped it to 6" of water and am getting a tea coloured skimmate, but lowering the water level in the skimmer just makes it so the neck gets choked with thick skimmate and none reaches the collection cup.
