Just a heads up in case anybody tries the above....the venturi valve slows down the flow rate of misters. Im going to play around a little more with it. Its adjustable so you can find a balance which i did. I don't have any way of testing amount of o2 without a meter and i don't have the cake. My guess is a larger pump probably wouldn't be as phased by it running wide open.
Ill update when i have time to play some more.
