That is a stunning tank... it is an ADA setup, with high light and co2 injection. The whole setup would probably set you back around $2500 when all is said and done...
Grass-like plants are some of the more challenging plants in the hobby. On top of that, that tank is painstakingly manicured. It does not all grow in like that at the same height. It has to be scaped. It requires some very good lighting, and careful balancing of aquatic fertilizers.
There are lots of great links in the resources and references sticky in the main plant forum here. If you are interested in planted tanks, that would be a good place to start. It will help you gain an understanding of what is involved in successfully keeping planted tanks of varying levels.
