here is another vote for this tank being cycled already.
Gray808, you used live sand and bottled bacteria and its been, what 3 weeks? You've seen ammonia go down, you have nitrites and nitrates present... You tank is cycled enough to start adding a light bioload of fish if you so desire. I'd do a water change first though.
I started a brand new tank recently too, using all new dry rock and dry sand, added bottled bacteria, and my tank was cycled in less than a week. I waited an additional two weeks before adding my first fish, but I'm pretty confident your tank is cycled by this point too. You started off with more bacteria than I did since you used live sand.
