The number of bubbles needed depends on too many variables for any standard
to exist, but a good general way to start is with one bubble per second.
That usually won't change things too rapidly or get out of control before
you can catch it. Watch your pH and KH and try to get the CO2 content
somewhere between 10 to 25 mg/per liter using the charts on the Krib


Typically, you'll want the pH around 6.8 to 7.0 and the KH around 3.0 to
6.0, but this will depend on your inhabitants.

FWIW, the CO2 content in my tank is a bit on the high side (25-30 mg/L) and
have not seen any ill effects since I've been using it.
