KNO3 Dosing question

Hi Guys,

Quick question:

I have a 454G bottle which reads "Humco SaltPetre Potassium Nitrate Purified granular for technical use only"

There isn't an ingredients list, which leads me to believe potassium nitrate is the only ingredient.


Is this safe to dose in my tank?

I am not sure why you want to use this considering that it only costs $3 for a pound of KNO3...

Humco Saltpeter Powder is a natural mineral with many uses in commerce and in magic. It is employed to preserve foods, to make powdered incense burn more evenly, and as an ingredient in Gunpowder (which is Saltpeter, Charcoal, and Sulphur.) It also has a reputation for diminishing the male sex drive when ingested, although this is not backed by scientific evidence. Magically speaking, Saltpeter has a long, long, long history in hoodoo as an agent of magical protection in spritual baths and floor washes and as a shoe-sprinkle. Also, because it is an ingredient in Gunpowder, it is used in formulae which are hoped to produce quick ("explosive") action, such as Block-Buster. In this capacity, it can be an ingredient in love spells or money spells where fast action is required. (There are also certain "explosive" spells that call for Gunpowder as an ingredient, and if you cant find gunpowder locally, you can use Saltpeter, Sulphur, and Charcoal to mix up your own Gunpowder for use in such spells.)

Thanks for the response and the information, however I'm still not sure from your post whether it's safe or not.

I want to use it because I already own this, it's sitting infront of me right now! =)

Try and see if you can check the MSDS for it, hazardous substances will need to be listed. It seems from the title it'd be 100% KNO3, but unless someone that has used it posts, we'd all just be guessing if we said it was okay.

Thanks for the MSDS tip, I checked and on the MSDS sheet it has listed:
Component: Percent:
Potassium Nitrate 95.5 - 99.2

Nothing else is listed... so it says it's the only ingredient. But what about the other percentage points?

Yeah, that would be a red flag for me. I'd not use it.

If I recall correctly the MSDS for Spectracide Stump remover lists it as 100% KNO3.

Yes, just checked, listed as 100%. The missing percentage points may be things like anti-caking agents, etc, not something you'd probably want in your aquarium.

You can use it, it is KNO3, just labratory grade, it is almost exactly the same thing you get when you buy a pound of KNO3 from one of the many people that sell it around here. The stump remover is 100% because they buy KNO3 from a supplier and they don't add anything to it, just package it up and sell it. So they can say it is 100% KNO3.

Aquascape? I'm a crypt farmer.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

Ahhh, perhaps that explains why my K2SO4 appears to have sand in it, heh.
