Cycling a tank

[Summit09]

I've just started my first reef tank four days ago. I went and did a water test today and found 0 ammonia, nitrates at 5 or less, nitrites at .1 or less. The live rock in the tank has been cured, as for the live sand it did have a smell and I thought it would be enough to start a cycle. Should I have seen a rise in my water parameters already or may I have to add something to kick it off ?
