well for now i have the crappy nutrafin max test set so its not exactly the most accurate test set. and i consider high like 20 and above. However i just washed my test tubes, and water syringe really good and re tested, and now it shows 5 or less nitrates, but it still is higher than my nitrites. Just proves how accurate it is. I do a 5 gallon water change once a week.
