Were all of your rocks base (Ie dry and dead) or were any of your rocks live? Also, when you say live sand is it that stuff you buy in the bag, or was it from another tank?

As DM said, throw a dead shrimp in there and that will kick off your cycle full swing. You will see ammonia spike and as it stars to decline, nitrite will spike and as nitrite starts to decline, your nitrate will then start to spike. Once that happens, your tank will have finally started maturing.

I strongly reccomend finding people who live around you and see if you can get a cup or so of their sand, the more the merrier. Also, most LFS will sell you a lb of sand from their tanks pretty cheaply. I'd try to get as many as you can. That will ensure your sandbed is nice and seeded with a lof of life.

The sand you get in the bag is very questionable as to what it contains other then some bacteria.
