Update: 2L yeast reactor piped into a power filter and emitting a fine
bubble spray of C02 equals 3 inches of growth on an anacharis bunch,
almost 2 inches on some didiplus, and a red tiger lotus that has leaf
veins popping out like the Hulk and possible pearling (not quite sure
what that looks like, but I see bubbles on the leaf underside.) Now if
I can just get my nitrates down to the 5-10 ppm range, I will be one
happy fishkeeper.

Watching the corydoras doing their hoover act on the new growth is too
much fun. I'm realizing how dorky that sounds as I type it, but hey,
you people will understand. : )

Peace.
