Hi everyone,
Needing some help to interpret these test results. I have been hearing concerns about the purity of PC SN (I purchased mine last Aug and it has remained sealed in a cool, dark place) so I decided to test it via aquarium test strips. I performed the text exactly as the tutorial instructed. Only thing is, it's so hard to tell the nitrite levels, the colours are so similar. I used 3 different testing strips and posted photos of each. There are definitely nitrites present and looks to me like the colour shows consistently around 5, but I could use some extra eyes to help verify. (Nitrites are second from the top in each).
Also, is it ok to use if it's not obviously 10mg/L?
Thank you so much!
