okay,
In order for myself, or anyone to help you out, you need to provide a little more information first.
Tank specs, equipment you have, what corals you plan on keeping, specific setup you have in mind (DSB, plenum, skimerless, etc), lighting, electrical, cooling/heating (fans, chiller), pump requirments (sump, sumpless), water movement (wavemakers, dump buckets, sea swirls, power heads), etc, etc.
In other words, give us your basic plan, and budget constraints, and we will be able to offer you more help.
