In regards to CO2, the aeration of water by skimming is normally for removing excess co2, from the fishies, etc. In your example of the concrete tank above the limewater created ate up the co2 to a great level.

My scrubber does more than enough air exchanging. And I'm happy with an alkalinity level at 125ppm.
