Carbon dosing will bring the nitrates down. I was skeptical about using vinegar, and vodka etc. So, if like me you want something tested in a lab, have a look at Red Sea's NO3:PO4-X. I have found this to be an excellent product, and you can really dial it in to get the exact level of nitrates you desire (which isn't always '0').
