Hey everyone,
Since I decided to test my SN, I re-read the "SN Bible" by Vizzy. I understood how to perform the test and have already ordered the necessary supplies (aquarium test strips and a milligram scale). However, out of curiosity, I fed their formulas to an AI (Gemini 3 Pro, for anyone wondering), and it pointed out that test strips are calibrated to measure ions (NO2 | NO3), not the entire compound (NaNO2 | NaNO3). In NaNO2, these ions make up roughly 2/3 of the weight. This means that if you perform the test exactly as they did (two cups with 500ml of distilled water and 2.5 grams of SN), you would get ~6.7 mg/L of NO2 in the second cup, not the target 10 mg/L
So basically, in their photo of the results, the color should have been a pinkish shade (5 < 6.7 < 10), but their result looks even darker than the bright pink for 10 mg/L, almost reddish...
Overall, this seems easy to correct: instead of adding 1ml from cup 1 to cup 2, you would just need to add 1.5ml. That should give you a 10 mg/L of NO2
(for this purpose, I purchased a 1 ml insulin syringe; I'll add 1 ml / 100 units first, and then another 0.5 ml / 50 units. I'm going to run both tests out of curiosity)
Can anyone confirm this? Or debunk it? What are your thoughts on this?
