My little contribution to this thread (which is one of my favorite threads on Reef Central).
20" cube largely prescribed by "ninjafish" who posted detailed descriptions on nano-reef.
The only visible equipment is an intake 'hole' that you can see in the up close tank shot.
It's a closed loop with an eheim pump, an inline chiller and heater. Filtration is water changes and a remora bak pak that I put on a couple nights a week and take off in the morning-- I can't stand looking at aquarium equipment.
I'd like to deal get a better looking light -- I tried the Giessseman pendants for nanos, but they were defective. Any ideas? The 20" of the tank makes a small light a must, but I love the 250W MH.
I still stink at close up photos. And there's still a lot of growing to do. It's only 16 months old, and has endured about 50 rock changes as I finalized aquascaping. I really believe 'less is more' and don't know why it took me so long to figure it out.

...sorry this one's a little fuzzy -- just got done scraping algae, and there's some cloudiness in the water.
