Aquascaping

Over the weekend we got a new fish tank. It is a corner unit due to the size (350 litres) we only just managed to get it into the house. I am now looking for ideas of how I am going to set it up and came across this video of the international aquascaping competition.

If I was able to set up something half as spectacular as these tanks I would be delighted but my Silver Dollars would not as they would be moving home.
