hmm. i never set up my own salt water reef thank before, but what is it that is hard to replicate?
The tanks done by Amano are fantastic looking tanks, but they are also highly contrived. In other words the tank is set up to form his ideal view of nature.
A SW system with live corals is going to grow more or less the way it wants to. Sure you can do the initial setup, and some pruning, but you can't control it the way you can in a FW planted tank.
