Using chemically suppressed ion chromatography, trace nitrite and nitrate are accurately and rapidly determined in drinking water. …Identified nitrite and nitrate values are 0.0, 0.25, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0 & 10.0 PPM. This kit contains everything an analyst would need to perform a water test either in the laboratory setting or out in the field.

Continue to measure every day. The exiting part is when you test one day and ammonia has been reduced to zero (after you dosed 2 ppm the day before) and Nitrite is also reduced or eliminated! That is the official test to pass in order to be fully cycled: Dose 3-5 ppm of ammonia, test 24 hours later, and the result is no ammonia and no nitrite!
