Honestly, my pH hasn't dropped with either the bell or the Hagen

That's weird. How big is your tank?

Twenty gallons. Thirty pounds of Flourite substrate, but I don't
believe that Flourite has any buffering capabilities.

If the CO2 is getting into the water, I'd expect to see a pH drop.

Me too. It's held steady at 8.2, however.

I'm using an Eclipse 2 hood, which makes for some turbulence at the
surface, which could be impacting the CO2 reading. I'm planning on
tests and water change later today, so we'll see if anything has
changed.
