The difference in volume created by 15" of water depth is miniscule -- you
shouldn't be able to observe it. If you get a real difference in the
CO2 output then it means you have a leak.
Another alternative is that with the outlet near the surface you get more
frequent, smaller bubbles and with the outlet deeper in the water you're
getting less frequent, but larger bubbles. If you judge the CO2 volume
just by the bubble rate then it will look like you're getting less CO2
with the outlet deeper in the tank, but you aren't.
