For a faster response time, couldn't you hook up a small air pump to pull air from inside the checker and into the water in such a way that it bubbles back into the checker?

I'm not sure if the diffusion times for CO2 from water to air would be enhanced enough to warrant going through the trouble, but I thought I'd just throw it out there.
