CO2 O2 and aeration

I did a search and couldn't find this topic covered specifically. I hope I'm not repeating a previous discussion.

Tom says in another post "CO2 goes into and out of solution with water very easily"

and there is more CO2 in air than water, so wouldn't using aeration, which just pumps air in to the aquarium, put more CO2 and O2 in to that aquariums water, than an aquarium with no water movement?

I may be mistaken because my memory is less than perfect, but wasn't Ole Pedersen saying in his talk a couple years ago at the AGA convention that creeks with a lot of rocks and surface movement had higher levels of CO2 because of that. Wouldn't the same be true in an aquarium or have I missed something?

Not that I plan on starting to add air or filters or any of that sort of thing on my aquariums, lol this is all hypothetical conjecture.

 

I'm sorry I worded that poorly. Hypothetically if you had a 10 gallon tank sitting full of water and a 10 gallon tank sitting full of water with a running small bubble air stone, which would have more CO2 in it?

Wouldn't the one with the air stone because it would create more area where the CO2 could dissolve in the water?
