Refugium question

[reefy]

I just finished intalling a custum made 30Gallon refugium 2 days ago its running fine so far, my question is what should I put in there, I have around 40 pound of live sand around 5 inches deep and 3 pieces of spare live rock thats about it. now what else should I add to it?I am getting a T5 2X54W today; is that enough lights? I was thinking to put micro algae. any lifestock eg shrimp, gobys, snails? but the thing is that my refugium is at the back of my tank so I wont be able to see anything.....thanks in advance for you suggestions.
