Jose,
I agree with you, BUT this is a science - some of us just have blind luck (me for instance) and others have the hand of death.
FF - this can be accomplished for under a $1000 I believe (not including livestock).
Best way to do things is to start acquiring rare specimens (costly) and grow them out. Like Purple Monster, or rare Danae's etc. Even some of the powder blue acros, even Acan Lords would be good investments.
You will need to monitor this tank daily, for signs of weakness, and have a back up (read stable here) tank to put frags that seem to not be adjusting.
The other thing that no one seems to have touched here is that the biology of the animals is very important to consider - they will stage warfare against each other and some will live and some will die - so, choices of corals, locations in this tank, etc is critical. keeping in mind that the specimens we keep don't usually gorw next door to each other. What might be better is research on where a specific corals that you want to propogate grows and try to simulate it's environment as close to that as possible - including the other corals from that area.
Oh, yeah, skim the S*** out of this tank.
