You also have live rock, correct? Assuming you do....
With live rock and live sand you should have very little cycling process. You already have all of the beneficial bacteria which you need on the live rock and sand. Sometimes there is some organic decay from deep within the rock, so i would suggest waiting a week or so while testing for ammonia and nitrite, just to be certain that your levels will not elevate. If both ammonia and nitrite stay zero, then you can begin adding fish. SLOWLY.
If you do not have live rock, then you will need to cycle your aquarium the traditional way. The live sand will help "seed" the biofilter, but you will still need to allow colonies of bacteria to grow on your biofilter to support fish. You can add "starter" fish, such as Damsels, to cycle the aquarium. Or, you can also add ammonia to the aquarium directly. ( Google the topic)
Or you can add some live rock, which is the preferred method today.
Either way, be sure you have a list of fish up front. You will want to add the fish to the aquarium in a specific order, based on compatibility and territorial behaviors. (ALL fish exhibit territorial behavior to some degree.)
