This is exactly my results - in fact it can pull out more in 24 hours than it used to make in a week. But the skimmate is definitely lighter. I used to pull out "Coca-cola black" skimmate, now it's more like "green tea".

But I wonder if it's not unreasonable to expect a lighter skimmate than before, if you're pulling it out faster maybe there's less DOC to pull out?

Because that my airflow hasn't increased and it doesn't appear to be a more voluminous (is that a word?) foam (like what others are claiming on RC), I'm reluctant to try lowering my water level (by opening the gate valve) too much because I'm afraid it will hit a threshold and basically stop producing skimmate. I'm still planning on modding the venturi and maybe the volute to see if I can pull the air volume #'s up a tiny bit.
