Wait, wait and wait some more. You can do the stock tests, ammonia and so on, but you need patience. If you can put in some more live rock and avoid putting any fish in for at least 6 weeks you'll save yourself a lot of hassle.
When you start a live rock tank it takes time and lots of it to stabilise. Various waves of growth and death take place in this time. Have you had a diatom algae bloom yet - no. Any green algae yet - no . No cyano yet no. All these things will happen in your tank, and it is best they happen in a tank with no fish, as it makes the inevitable algae blooms so much easier.
So accept you'll be a while without fish. Do some reading , and enjoy the lifeforms on your live rock. If you get bored add a small shrimp. It sounds tough, but believe me it's worth it.
