Resource Stability of SN and N

[EmptyBottle]

My SN just arrived but the fucking custom opened with knife and taped it back... Will It be ok? I'm so furious right now...

test it, to ensure it is not inert, aquarium test will do imo

Iv had mine (in solid form) for just about or just over 5 years sat in the cupboard in the bag it came in in an airtight box. It's now in its bag in a vacuum sealed bag in a mason jar with silica gel packets. However I had some in just a zip seal bag on its own that had been in the box too, just tested a gram in 100ml and my test shows pretty much exactly the same as yours.

Think the mix needs to be diluted with the aquarium test procedure to not saturate nitrite and nitrate

Should be okay but I'd transfer it to another container. You'll want to test it regardless.
