Red Sea Pro Nitrate Test - High Range?

You do understand that the number on the wheel is opposite the color, right? Not next to it. Stupid design

That is exactly what i did not understand! Thanks! So, second to lightest shade is 0.5 ppm, correct?

Good test kit for low range now that i understand what the colors mean!

Adding 2ml a day of nitrate im at 0.5 ppm nitrate in the 20 gallon nano. Visually corals look happier than at undetectable. Green slimer has better color. Phosphates lowered on hanna checker with nitrate addition from 0.13 to 0.09
