After dosing 5ml of KNO3 for a 37g tank, test kit remarkably read 0ppm

tank: 37
solution: 250ml
teaspoons KNO3: 10

1ML = 0.98 ppm/37g

Dosed first 5ml two nights ago,
last night NO3 was checked with the red sea kit and the reading was "0".

Then dosed another 5ml KNO3, kit still says "0"

What up with that ?
