I have been using this Nitrate test kit from Nutrafin....Its two years old. I have been getting consistantly high looking reading that did not truly match the color scale but looked ominously dark. I have been doing VERY frequent water changes as i know I am somewhat over stocked while my 150 gallon project wraps up......The kit finally ran out of test so i bought a new one......API kit.

My levels are 5.0 two days after water change! I thought I was going crazy! My water changes barely effected my Nitrate levels before.

Never new a test kit could go soooooo bad! Lesson learned!!! Could have saved a few hundred gallons of water!
