co2, rather than fine bubbles, fine mist of water?
if you had a bottle turned up side down and held under the water and this had your tube from the co2 reactor running into it so that it was filled with pure carbon dioxide then below this you put an atomiser as used in little pond bowl decorations this would create an extremely fine fog of water in the bottle of co2 so surely the tiny water droplets would absorb a lot of co2 as they travelled around the bottle before re-condensing into the water again? yay or nay? just an idea i had because i broke the little thing that held the tube in front of my pump and i have one of these atomisers. NOW it does say not to use with animals i think but theres none in my tank yet so i just want to know if it works in theory.
