Re: CO2 and O2
Tom, you said "We pump CO2 gas and dissolve it well going far beyond the
saturation level." I'm not sure what you mean by this -- with O2 we get
supersaturation and pearling (around 10 ppm), but water can hold *far* more
dissolved CO2 than is safe for our fish. I thought you can get in excess of
1000 ppm CO2 into (seltzer) water. Or do you mean (plant) saturation with
regard to their carbon needs?
