Hello - I have the API Master Test Kit but the color is unclear.

I was testing my nitrite levels before adding shrimp, but I couldn’t tell which color it was..? does anybody know what this color means for nitrite??

did you do the PH test on accident? I would say that this is between 0PPM and .25PPM and closer to 0 than .25
