I use a power reactor, which dissolves 100% of the CO2 in the water (as
evidenced by no visible bubbles coming out), so I have no experience with a
diffusor. Visible CO2 bubbles in the water, and especially on the surface,
are evidence of incomplete dissolution. If your CO2 concentration is
adequate, as calculated by pH and KH, then you don't have a problem, unless
you find the bubbles unsightly. If the CO2 concentration is inadequate,
then you definitely want to work on getting more of that CO2 dissolved and
less escaping as bubbles.
