The simplest way to get the CO2 into the water is to use a dome. You
just trap the bubbles that don't dissolve to give them time to
dissolve. For my 55g I cut a 3 1/2" square plastic food container
down to about 1" deep. Using 2 suction cups I held it inverted near
the top in the back corner of the tank and placed by CO2 source under
it. For smaller tanks I used domes with smaller areas. In time air
will collect in the dome and you may want to release it. However, I
found that because of the high solubility of the CO2 it's really not
necessary to release this air.
