I have a 20 gallon
sump under the display that both the
frag and display tanks flow into. I have a
refugium section in the
sump with mixed
macroalgae. Here's a pic of the crazy plumbing going on down there.

I'm using a single Quiet One 6000 for the return.
For lighting I am using two 250MH w/XM 10k bulbs and 2 110w
actinic vhos for the display. The
frag tank has a single 400w
MH w/radium bulb.
Skimmer is a
DIY that sits in the
sump. Maxi-jet 1200 running through it with a
diy needle wheel.
For livestock I have one percula clown, one yellow tang, one sailfin tang, a mandarin goby, two chromis, a serpant star, a coral banded shrimp. A ton of mini-carpet anemones, a large 14" diameter seabae anemone, a bubble tip anemone.
For corals I have about 30+ types of zoanthids. You can see some of them here

For sps mostly
acros and monti's. LPS candycane, enchino, a hammer, and couple others. A mix of mushrooms and other softies.
Heres a few more pics:
