I have the sump buddy 60 and have always had tea green skimate no matter how I adjust it. I have it powered by a Rio+ 2500 (large pump). I tried and even larger pump and it still did the same thing. The bubbles just never make it to the bottom of the skimmer. I guess like you said, the "High Pressure" aspect of the pump is very important with these skimmers.
So I ended up buying the Coralife turbo sea High pressure 793. It has essentially the same specs as the Iwaki WMD 40RLT that ETSS recommends to use with the sump buddy 60, but a little more in my price range. I hope this helps get all of those bubbles to the very bottom of my tower like it is shown on the ETSS website.
Maybe then I can produce some REAL skimate instead of grean tea.
