I have 3 packages of SN in total, one from an international MNC and 2 from local brands. I trust the MNC one would be good as it should be manufactured to a good standard.. I dunno what testing it on receipt would do for me anyway.. I am paranoid about the SN going bad by the time I CTB.. so the only thing that'll reassure me is right before.
Not sure where you are from.. I am from India, so we might be looking at different brands.. The Salifert one luckily is available on Amazon here though, and I intend to order that soon.. There's one called the API nitrite kit and QPETS which looks like the strips you've used.. Guess I'll be using one among those three.
Exactly.. I asked an AI chatbot about this and it said that these aquarium test kits are not reliable or accurate and suggested I test it in a laboratory.. Right! Like I have access to that..
