I have a Penguin filter with 2 biowheels on my 55 gallon planted tank and I
use the 1 bubble/second rate. It keeps my pH at a steady 6.8. As someone
else has said, if you keep the water level up, then you don't get a lot of
CO2 loss (in my experience); if I let the water level drop too low (I get
lazy sometimes <G>), then I do see the pH rise a bit, leading me to believe
the CO2 is getting lost more.  Just my own experience....
