o2 or not to o2

 The gases don't preclude each other from being in the water.   The
answer is to be found in Henry's Law of Partial Pressure.  The amount of
any dissolved gas is directly proportional to the partial pressure of
that gas above the water, thats why co2 dissipates so quickly because as
you add it to the water column it creates an imbalance. Adding more co2
is not at the expense of o2 its in addition to o2 and any imbalance is
corrected from the o2 in the air.  The plants take in co2 for
photosynthesis and give off o2 thereby adding an abundance of o2 also.

-> Hi,

-> Could someone please explain how I can pump in carbon
-> dioxide but still have (supposedly) 100-110% oxygen
-> available at peak photosynthesis? How is it exactly,
-> that the two exist exclusively of each other?

-> Also how can I make my Crypt balansae take off? Its
-> growing very slowly.

-> TIA
