Help Nitrite test: can I use an aquarium test?

[That's Not Me]

This post is part of a series of posts that I will do to answer some pointed questions. Please forgive me if the topics are repetitive here on the forum, but I don't have the search option yet :)

I will test the nitrite first to be sure, but first I have to buy the test. Do aquarium tests work normally, or will I need one of those more expensive blood tests?
Here in my country there is a reliable marketplace where the products arrive the next day and make it possible for me to arrange to receive them personally to avoid suspicion, but I would like a second opinion about the products. Could someone check? https://produto.mercadolivre.com.br...hY2MxMDYtZWIwMy00ZmE4LTkyZjYtNDRkNGQxMzBmNTcz

Thanks a lot

Oh shit... I didn't know. Why do I need to test it?

Aquarium test works better than home blood test. Please use the search bar for technicals.

The best one if you order lab test (example: by Energy Control).

I think mostly for peace of mind. I know some people have mixed a little of it with a bit of their blood- I believe it turns it a brown colour. There's been some debate on whether it's wise to open the container though if you don't intend to use it for a while. I'm really not all that knowledgeable to be honest though- so- best to research everything you can if it's your chosen method.
