Help sn test strips

[wanttodie12345]

I'm going cross-eyed trying to decide if there is even a difference in shades of pink on the bartovation vial, let alone which one matches my test results. Is there a different reliable brand of nitrite test strips that's easier to read? Or is there a way to adjust my test method? I followed vizzy's guide.

I tried again and got even more confused! I tested plain water and the strip turned darker than the strips dipped in the sn solution! Not sure if I need different strips, different sn, or if I am doing something wrong during the testing process.

If the strips 'darken' (i.e. 'colour') more in the water than in the sn mixture, I fear that you have a problem with the water or with the strips... As an alternative, there are also "drop test kits" that are perhaps even more sensitive and specific.

Thank you! I was also thinking it could be the strips. I only did one strip in the plain water, I should have done more. So far, the drop test kits seem complicated, but I'm going to keep searching.
