No detectable nitrates leads me to believe this tank is not cycled. Not a big deal, really, just do water changes as needed to keep the ammonia where you want it and the tank will complete its cycle in time.
Well I did a small water change and decided to let the tank do its thing for a couple days... happy to say Ammonia is back to 0, Nitrite 0 and Nitrate less than 5! Thanks for all of the advice
