If you don't understand what I am getting at, I will not try explain further. I have hijacked this thread enough.

Actually a skimmer serves to oxygenate the water by producing fine bubbles that take longer to reach the surface thereby increasing the contact time with water and increasing the oxygen content of the water vs. larger bubbles which jet to the surface much faster and have a more limited contact time.

Again you don't understand the premise. I cannot explain it better, but no it will not happen. Simple concept known as surface tension keeps it from happening.
