Answer:	The colors are as follows: Yellow = 0 mg/l Yellow/Orange = 10 mg/l Orange = 25 mg/l Red = 50 mg/l Burgundy = 100 mg/l or above
Question:	Who do I complain to about the fact that my kit didnt even come with the needed tools? In order to test, you need the "measuring spoon
Answer:	My test kit was packed in plastic envelope instead of a box. Consequently the box the kit came in was crushed. When I removed the box, and was about discard the envelope I noticed the vial of powder and the little spoon in the bottom of the envelope about to be lost. That’s what might have happened to you.
Question:	For anyone that uses this....is the #3 powder suppose to dissolve completely
Answer:	And because it doesn't totally dissolve, when you add the drops from vial #4, make sure you time out to 5 minutes and then check against color chart. After 5 minutes, the color level will increase the longer it sits there. The accurate reading is at that 5 minute mark. I've left the vial sitting there while I did maintenance on my tanks and after 30 minutes, the color of the liquid had changed to a higher level of nitrate.
Question:	Are the Instructions in English
Answer:	The kit includes instructions in half a dozen languages, including English.
