I think we need to hammer this one out, because I didn't do a good job of describing the phenomenon when I wrote the "aeration simplified" archived thread. Do we have specific literature on what appears to be a "surface diffusion vs. phytoplankton delivery" issue that needs resolved? If so I'll amend the archived thread so that it's more accurate. It's obvious that I don't fully understand the concept. I also just figured it was a air/water interface diffusion and hadn't considered phytoplanktons role.
