Ok now you need to start your cycle. For the cycle you need to have the lights on for about 10 hours a day and off at night. The cycle will take a couple of weeks (no matter if you have live rock and live sand, which usually says in the bag instant cycle) after testing the water and having amonia at 0 and nitrites at 0, you could say that your tank is cycled, then you can start adding your cleaning crew ( hermits, snails, and/or shrimps). You have to wait a few days for the cycle to kick off, sometimes if you test the water the day that you set up your tank or the next day, the values might be at 0. This doesn't mean the tank is cycled, because it might take a couple of days for the process to start and then your amonia is gonna go up as well as the nitrites. Hope this is helpful and keep posting your answers there is always somebody with the right answers.
I forgot to ask, what is the size of your tank?
ps. btw you could read blinky's nano-reef diary and you'll get and idea of the process.
