Has anyone ever thought of creating a CO2 diffuser made of a long tube coiled around where you have bubbles flowing up the coils and the water flowing down? It seems as if you could achieve 100% diffusion pretty easily. Any thoughts? Anybody ever tried this?
That's a an old concept if you ask me as reactors of the past and even some today employ a similar concept, albeit different design.
I can tell you from my experience effective diffusion is when your design allows for an area where water and Co2 is mixed vigorously while having the least amount of micro bubbles escape you chamber. Don't get me wrong bubbles are good, but for aesthetic reasons the less the better.
