So I keep testing my nitrates and for the first hour it's yellow. It isn't until about 8 hours later that the color begins to darken into 180ppm. Is that normal? I shake bottle one for 30 sec add the drops than shake the test tube and the bottle 2 for 30 seconds than add than shake the test tube for a minute than leave it.
Anyone else have that happen to them?
