It really does what these guys say. I saw it in action. It _does_ produce
lots of _very_ fine CO2 bubbles that are small enough that they _do_
dissolve before reaching the surface if placed near the bottom of the tank.

Would that lower the pH? This thing does.
I'm not convinced that it is ceaper than a DIY pressurized system, but it
was pretty neat, and has the advantage that there are none of the dangers
of a pressurized gas cylinder. Of course you do have potential electricity
and water hazards...<g>
