My first SW tank...and it's a nano!

In such a small tank, it probably won't make a difference either way. The tank is too small for a deep sand bed (DSB), so you'd probably do best keeping the substrate as shallow as possible. The depth of the sandbed in the first picture looks about right, IMO.

Maybe I'll upgrade on the lighting a bit more. I'm not quite sure how I should upgrade though.

Coralife 50/50s. I've been using those for over a year in my nanos, and they work great for soft corals. They screw in to medium-based lightbulb sockets. Two 20W bulbs might be overkill; that's what I use on my 6 gallon tank. A 20W might do it, or maybe a 20W and a 10W?
