What is the best Frag setup?

[jake]

I want to set up a frag tank and I have been giving some thought into building a shallow wide tank much like a table. Will this work for a wide variety of corals or will I need several tanks with different conditions? You see I got the idea for a table like tank from a store I frequent back home. The tank they have is quite large lets say 15 in deep, 3ft wide, and 10ft long. I won't ever need something of this size but whoa wouldn't it be nice. I am thinking of a smaller system with the same concept. Any ideas or advice?
