adam,
Welcome to the club. What nano cube did you get? I have the orignal cube. I have made many mods to mine. I added a 96 watt powerquad to mine and gutted out the filter section and changed the pump to a rio 600 and put 14 pounds of live rock rubble in the filter section and have 12 pounds of live rock in the tank. I bought my live rock from MS in reston there was all kind of life on it. You should also go on to
www.nano-reef.com it is a very good site.
