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

I have changed the gravel already, I didn't like the black either. Now I am using crushed coral. It's much better. Though I've been reading lately, sand is better than coral. So many things to learn. Maybe I'll upgrade on the lighting a bit more. I'm not quite sure how I should upgrade though. It seemed like some of my corals didn't like the actinic bulb... I dunno why.
