Help How to check my SN correctly?

[kokporn]

I tried to check with a drop of blood but did not notice any changes. There is a smell of bleach and yellow color

I've never heard anyone say anything about a bleach smell and your blood didnt change??? I wouldn't use it

Wait, are you sure that's Sodium Nitrite with 95%+ purity?

 

[I screwed up]

Bleach smell is a new one ... But without change in color u may be risking it buddy. Even with lesser purity some colour change is to be expected

Buy a nitrite aquarium test:)

I agree. Definitely test it a second time to be sure.
