The book in the tank must be recognized by you all.
You'd be amazed how many people try these tanks without actually reading the book :P
There is only one pitfall. I want to create something which also echoes a hillstream...
Not quite a pitfall, just a scaping challenge...
I had a hillstream-esque image in mind for my tank
The foreground is Echinodorus Tennllus, background is dwarf sag.
No reason NPT has to be a crazy jungle... Just gotta balance things and make sure you got enough roots to occupy the substrate to keep it from going anaerobic.
If you think your pitfall is not enough plants in your scape, just stick an internal filter with some biomedia. It's not really cheating...
Also, remember that Walstad advises against any surface agitation. I see a lot of people ignoring this.
