bubbling
Hey all,
I'm brand new to this list and have a very basic question. I have a
fairly new set up tank w/ CO2 Injection, a flourite substrate and 4 watts of
full spectrum light per gallon. a few of the plants include Val., a large
sword, a few pygmy swords, and anacharis. My plants seem to be growing quite
prolifically, yet I never see them bubbling. Should I be concerned? I don't
see how photosynthesis can be occurring w/out putting off oxygen. Thanks
