Review on Accurate Nitrate (NO3) Test Kit for Optimal Water Monitoring - Salifert Nitrate Test Kit by Jeremy Jackz

Not only is this test faster, it is easier to use and more accurate than any other test I have used. I've been in the marine hobby for over 10 years and have used Red Sea, APIs and a few unnamed. None of them compare to the Salifert test. I will buy others I need. The best thing about the nitrate test compared to others I've used is that this one clearly shows zero nitrate, while others can sometimes be difficult to work out which color actually means zero.
