Is Spectracide 100 percent KNO3

[SamsReef]

hello friends,

Does anyone know if spectracide stump remover is 100 percent pure potassium nitrate or if it has impurities. Has anyone used for long period of time and done Triton test to see if any unwanted elements are accumulating. Appreciate the input.

Every chemical has impurities, but the safety data sheet claims it is 100.0% potassium nitrate.

FWIW, it is easy to buy food grade sodium or potassium nitrate, and I’d prefer that from the standpoint of quality assurance.

i was thinking about using it , but for a few more dollers there are kn03 made for fish tanks which seems well spent the mind set aside for a couple of dollers

Personally, I'd get food grade since the fish companies often state no purity or grade.

Thanks Randy...for confirming my suspicions...

Let me know what you think of this -

I've used Spectracide in the past with no ill effects. Food grade will most definitely have higher quality control and I think Randy recommends NaNO3 to KNO3.

I did not see any good food grade NaNO3 on Amazon. Does someone has a linky linky

That’s a good choice. [emoji3]

Thanks Randy for confirming. I have ordered it. Will try and update on my build thread...

From dosing perspective, I think I should be able to use the same calculations as stump remover...

8 tablespoon in 1 gallon and dose around 20 ml for 1 PPM increase in 400 gallon. It’s not exact but a rough calculation. Thoughts?

Here's a sodium nitrate:

For KNO3, you can use this calculator:

Thanks Randy. Always a thorough response.
