First of all, thank you for a very interesting post!
I think we are not all imagining the same thing when we use the
terms "light", moderate" and "heavy" planting. Certainly, a tank
can get so crowded that the growth rate drops off. I would not
term that "densely planted", I'd term it "over crowded".<g> Both
George and I have what I would consider "densely planted" tanks,
and I know from what I've seen of his tanks and what I've read
from him that both of us aim for optimum growth.
I may stress the term "densely planted" because I am so often
faced with helping a planted tank beginner who is having problems
balancing a 55G tank with two anaemic Swords, a bunch of failing
Cabomba and two bunches of "Princess Pine". To too many people,
that's what a planted tank is. At the same time I tend to stress
light fish stocking, again, because beginners tend to overdo it in
So maybe in your terms, my tanks are "moderately" planted, since I
do whack away at them with a machete fairly frequently.

I think you may be misinterpreting lack of meaningful input as
lack of interest.<g>
While I have had a number of Echinodorus species flower (and
produce plantlets, and once set seed) in my tanks, I always
considered it serendipity. I have never known exactly why it
happened, nor have I ever tried to get them to flower on demand.
I think it would be great if you would share what you have to
offer with the whole group!

That's one of the things that makes this group so much fun!
