where did you get the 99.8% KNO3 ? online ?@Randy Holmes-Farley
I'm wanting to make this way more concentrated. I'm not using stump remover, but pure potassium nitrate, 99.8% which I'll guess is same solution.
Going with the above formula for my tanks that I need to dose total water for 140 and 50 I'd need 70ml and 25ml to raise .08
Let's say I mixed 50g instead of 10g with 1l of water, would I be correct in saying I'd need 28ml for the 140 and 10 for the 50?
Appreciate your help in making this stronger concentration.
