More like guess the shade of pink or light purple. Why is there no hanna checker for nitrates ?
Great kit, scale to your needs By Eric on 8/20/2017

I'm coming back for a refill, so after many months of using the original kit I am still happy with it.
The kit comes with instructions for low range and high range
Low range resolution: 0, .25, .50, .75, 1.0, 2.0, 4.0
High Range Resolution: <4, 4, 8, 12, 16, 32, 64
Well I like to keep my nitrates at 2.0-4.0, aiming for 3.0. So with the 2 ranges given, neither are really ideal for measuring within the 2.0-4.0 range very accurately. On the low scale it's close to the top of the range, and it's not within range of the high scale. One of the things I like about this test is it's easy enough to make your own scale. With 4ml sample water and 12ml distilled water I can create an in between range with a resolution of <1, 1, 2, 3, 4, 8, 16. Now I can more accurately measure a 3.0 reading.
Other easy scales to create:
8ml sample water/8ml DI water = <.5, .5, 1.0, 1.5, 2, 4, 8
2ml sample water/14ml DI water = <2, 2, 4, 6, 8, 16, 32
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 test kit. Easy to read colorimeter. For nitrate, this is the way to go.

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.

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.
