Bruce can you comment on your experiences with growing some of these. I
have only a few species, but of the ones that I got off dave most of them
have done very well. The two limnophila's that I have (brownii and
australis) have done very well as has the pogostemon stellata. I had
previously got some najas tenuifolia and that is rather nice, it is
certainly not for someone with rough fish or for someone that does not
appreciate anything that looks different. The Marsilea species that I
have is growing like mad and makes an interesting addition to the tank.
The only problem that I have is really the aponogetons, they have not
grown as well as I would have liked. This is in a 3' tank with 100 watts
of light, CO2 injection on a pH controller and trace element addition
with a personal recipe that is now being sold here in the ACT. The pH is
7.0, gH 150ppm, temp 25, kH about 80ppm.

I don't suppose that you know anybody with those species?
