My thoughts exactly sir. The water and air "want" to be at equilibrium with each other, and once equilibrium is reached no amount of air pumped through the water will change that equilibrium. Thank you again!
Ok one more question. All else being equal, wouldn't increasing levels of aeration push the ratio more strongly back towards equilibrium (in this case higher CO2 levels)through increasing the surface area of the air/water interface?
Hi, first time poster. Here's the scenario. In a given vessel containing a given amount of water at a given temp, gases from the air will reach equilibrium with those dissolved in the water contained in the vessel. Now suppose live plants are added to the water. During the day, photosynthesis...
