Beautiful scapes Mellonman, Norbert Sabat and you've found the way to show great low-tech tanks, thanks for sharing.
Maybe these guys (the contest organizers, that is) should run an "only low tech tanks" contest maybe every 2 years, it would be very interesting.
I have a 82 gal low-tech planted tank and it has been an eternal trial and error, lol. I have crypts, java fern, bacopa monnieri, hygrophilla siamensis, sagitaria subulata, rotala rotundifolia and ammania gracillis. These last two plants are doing so so despite of the fact they are considered as high light species, surprisingly the upper leaves of the ammania have a tint of pink.
I have no recent pics, but this is how it looked in Dec, 2006 (now is very different):

I know it's not an aquascape, but I think I can learn to do it better with some help of the members of this website :b.
