Testing Kits for SN

[cyuj]

So i've done digging, and seen a few different ways, I've seen from the SN Bible that they used some sort of testing kit to test PH / SN and a few other things, im not really sure what that is, if anyone could redirect me to it (i've read the bible and i was a little confused about how to test), Im sorry if i completely missed it and didnt realize it but any help would be appreciated!


is what im talking about

Thanks for letting me know would there be anything i can do to actually test the purity? or do i just have to guess / take their word

I haven't tested it yet, as my SN is still on its way. So my knowledge is strictly theoretical and gathered from this place.
As far as know you can only make that approximate strips test. Well, and the "blood test" as well.

So it's better if someone more knowledgeable will reply here. I just pointed out that small guide that I'm going to try myself.

much love thanks for this post! Best wishes, will definitely do the blood test, that seems to be alot more reliable.

Typically it's done with a standard aquarium test strip, like those sold by the brand Bartovation; mentioned in the PPeH.

I don't think you should take the word of anyone here lightly. I would always try my best to verify information. That being said, yes, you can test the purity with the aquarium/strip/reagent tests. However, the test should be done according to steps laid out here (it's my post so take that into account, but it has already been posted in this thread):

Problem with SN testing information

I'm making this post because I'm worried that people might be testing their SN wrongly. If I'm right, then tests done with the method explained in the SN bible (and everywhere else I have found on this site) will lead to an underestimation of the tested SN purity. This, in turn, may worsen...

Most instructions before that post were simply wrong, as you can read in the post.

What the test tells you is fundamentally whether your SN is near 100% purity. 100% purity meaning that the whole of your product is SN (NaNO₂). So, if the color you get with the strips or with a reagent kit is near the color of your target concentration (target concentration being the concentration your solution would have if your SN was 100% pure), it means your SN is pure enough. These test kits, however, are not accurate: they tell you if the SN is near but not how near. I would suggest repeating the test with different target concentrations and different kit brands. They are most useful to detect fraudulent or expired products, not to measure the exact purity. For that you would need spectrophometry, as explained here:

SN aquarium purity testing

Ok i think i finally get it now (kinda). Allthough the color of square under 5 is like color of wet sponge, would be hard to tell the difference between 1 and 5 no? Anyway gotta buy all the stuff and tested it again. I will still post somewhere on the forum my results, cuz i'm always not sure...
