I dont know the answer to this question, but I was curious what you guy's think. On my orca 250 I noticed that it seems to work great if I set it so the bubbles pop in the first inch or 2 of the riser. The problem is the skimmate gets so dark and heavy that it is completely dry by the time it gets to the top. On the flip side if I set it so the bubbles break in the top two inches of the riser the quality and quantity of skimmate is very poor in comparison. I have been trying to find the happy medium, but it really seems most productive set on the low side, although very dry, at least in my case. This leads me to believe the skimmer cup and riser are actually too tall to get more productive wet skimmate. Wouldnt this also make the optional taller riser and cup available just make you a very nice 6 inch skimmer with a big reaction chamber. Just thinking.
