  • Good nitrate test By leepink23 on 4/9/2017

    Easy to perform but takes 3 steps so it takes about 9 minutes. Easy to read, if your nitrates are higher than the color wheel then you have to redo the whole test to get the high range.
  • Great By Ed on 1/4/2017

    Great test kit. Easy to read colorimeter. For nitrate, this is the way to go.
  • Love it By Tvos on 11/10/2016

    Love red sea products , always consistent
  • I don't like Nitrate tests By Ramon on 10/15/2016

    I wish nitrate testing was as easy as alk/cal testing. However, coming from an API test kit, this is much much better.
    I always ended up getting reagent on my hands with API, not so with Red Sea. Although it's still a lot of steps, equipment is high quality, easy to use/read, and doesn't make a mess.
  • I am not a fan By Dan on 9/9/2016

    This is a pretty complicated kit to use in my opinion, I had to stare at the instructions for quite sometime to figure it out. I feel that it is difficult to accurately determine the correct shade of your water.
  • Great kit By Scott B. on 6/29/2016

    Product was as described. Easy to use and testing results readable.
  • Accurate, Consistent By Heavyreefer on 11/6/2015

    This test kit is very accurate and easy to read, I do have a Salifert test for nitrates but Red Sea is way easier to read and more accurate, the color shades are very distinctive and come in 0.25 ppm increments so it takes away most of the interpolation guess work.
  • Accurate and believable By Bruce on 5/13/2015

    Takes a little time and has a step or two more than other kits but it seems very accurate and reliable. The color wheel doohickey makes determining color very quick and easy. This is my third different nitrate test kit in recent times and I like this one best by far.
  • Good product By John on 5/3/2015

    First nitrate test kit for me. I wish there was a digital nitrate tester for under $300, but this is the next best thing. My only complaint is my tank water makes the result very different and hard to delineate which color it corresponds to.
  • Picture is not what you get By Douglas on 5/1/2015

    I ordered this test kit. It is a great test kit, but the picture is not what you get. The colors that you compare your test sample to are all shades of pink. The wheel does not have different colors, just light and darker shades of pink.
  • Very accurate By Alex on 2/5/2015

    This is a great kit, easy to use, and very accurate. It's helped me a lot with my reef keeping.
  • Easy to Read Test By Hasty on 11/12/2014

    Test is pretty easy to do and instruction card for doing test simple and easy to comprehend. The color wheel used in the test to get a reading takes the guesswork out of what the exact reading is . Love that color wheel. Other tests like API use a card with colors that you are suppose do match with the testing tube held near the color. The color wheel is attached to a plastic pointer like device that holds a control vial (clear water from your acquarium) and the vial that you put the chemicals into after completing the adding of chemicals and a waiting period of 9 minutes. then it is a matter of turning the pointing device until both vials match a color on the wheel, simple.
