I didn't reply because I don't meet your criteria -- I've had a heavily
planted tank with Flourite set up for, oh, about two years now. I've got
four flourescent tubes of lighting on a 75 gallon with occasional pop bottle
yeast injection. I don't add anything to the water column, but I've been
known to insert an occasional Jobes stick at the roots of a sword plant.
I'm happy with it. Growth speeds up, and slows down, generally depending on
whether I'm using CO2 or not. What else do you want to know?
