I totally have been wondering this myself. Like it seems if one keeps the wrap around it nonstop, then CO2 will become all used up unless you open it and freshen it up. I have thought about running an immersed setup with wrap around it and a CO2 airline going in as well. It will just keep pumping and work itself out as pressure builds. Seems feasible to me.
