KP,
Your cycle is nearly completed. Let the ammonia and nitrites wend their way to zero naturally (will happen pretty quickly). You may do another change to keep your nitrates under control, though I would expect your rock, sand, and macroalgae to take charge of your nitrates. Once ammonia and nitrites are at zero, give TBS a phone call to arrange for part II.
You will get a diatom bloom, and a small hair algae bloom. Those go away (esp. with all the hermits in the cleanup crew).
If you're going to keep corals, I would also test alkalinity and calcium. Supplement alk & calcium per test results. You only need to run calcium & alk. tests about 1/week.
Don't forget to do a periodic water change to help replenish trace elements in your tank and export crud.
