    Hi Rob

    sort of yes, but in a more confined space
    an airstone in the tank or sump, agitates a lot more water, than the venturi in the skimmer has access to

    your right though a skimmer does help with gas exchange, as do any Powerheads or returns that put ripples on the water surface
