Tank Setup

They told me my values but I didn't write them down. I will pick up a kit today while I'm out.

Back to my original question, will the set up I have support what I'm trying to do (reef tank with 2-3 small fish)?
 
Also, is my lighting sufficient?
 
I would remove the nano-bio balls if it were me and use the filter pad and carbon. If you can, replace the bio balls with some rubble of LR



How much live rock should I put in there? The bio bag is really quite small. And how big should I make the pieces? 1/2", 3/4", 1"?
