The CO2 bottling company guarantees 99% CO2 content. This is a fire
extinguisher bottle, so I suppose this claim to have some merit. Would
1% other gases cause buildup?

Is it possible that other gases dissolved in the water (like oxygen)
turn into gas within the reactor?

This reactor is supposed to remove insoluble gases automatically, but I
don't see how that can happen. It is completely closed, so I don't
understand how any other gas would escape.

Right now I am using one of the airstones that came with my eheim
airpump as a co2 diffuser. I have adjusted the size of the bubbles to be
fairly small. With this setup, I can reach the target CO2 concentration,
but the amount of CO2 fluctuates a lot and I need to supply about 4
bubbles per second.
