[Coral-List] using bubbles to remove CO2 from reef water

[Charles Delbeek]

Isn't this just the same analogy as trying to bale out a leaky boat?  It
just keeps coming back in.

Haven't read the paper but isn't this just the same as increasing surface
agitation ... how do they know the bubble absorbed the CO2 as opposed to
the CO2 just coming out faster due to the surface agitation caused by the
bubbles hitting the surface? Same idea as a deaeration tower used in large
aquarium life support system.
