Help me design this virtual reef tank?

[Jeremy Lain]

Hello, I was wondering if someone can help me design this virtual reef tank? So when its time to add fish and corals, I will not have any lost fish or corals. I will be making decisions based on opinions. I already have some equipment so I will be using what I have. The tank is a 30 gallon.

I will start by adding sand and dry rock. What is supposed to happen then and how long should it take?
