yeah, I hadn't thought about the gas exchange coming from the other end.

I'm seeing the a change in rate of pressure as it goes on. I'll post a graph later. I have a drop checker in a 29G tank to make sure CO2 is dissolved in the water. It does go from blue to green.

I was just thinking, this system is impossible to gas/kill your fish. The rate of CO2 is somewhat constant so this is another 'Pro'. Any excess CO2 would leave the chamber and out the tank without dissolving in the water and the rate of dissolving drops over time.
