Just being pedantic again, but the O2 comes from the removal of H from
water, not frojm CO2. Also it happens very late in photosynthetic
pathways, so any intermediary would have the same result,if that's indeed
where the bubbles are coming from. If that's what the folks from flourish
are claiming, then the scientific basis of what they are claiming is
seriously undermined. That's not to say that it doesn't work, just that
they might not have a clue why.
