You also feed orders of magnitude more than I do, I'm guessing, or at least the smaller sized food particles, more likely to be skimmed out if they're still floating in the water column. I probably get more of a dry skimmate from mine, mostly due to the fact I've had way too many issues of skimmer overflow and it's better for my sanity if the collection cup doesn't fill up to quickly. Unsure how much that actually is, but I don't think my skimmer collection cup is that large. From my last cleaning it's probably been 3 days and my ASM G3 skimmer cup is half full, so I'll probably clean relatively soon.
