Believe me, in ANY closed system, you'll have no problem exceeding NSW levels for dissolved organic material, skimmer or no. BTW, DTs claims that protein skimmers do not remove a significant portion of their product. I'm not sure what to believe about that, but I can say that the skimmate on my old skimmer did not seem turn green or change that much when I dumped in DTs; but algae paste was a different story. I'd heed JimD's advice about the O2 levels, although, if you're dripping kalk, you probably don't have ph issues to worry about.
