Saltpeter *is* Potassium Nitrate (KN03) as far as I know. Just make sure 
whatever you buy is pure KNO3.

I do know that Lily Miller's Stump Remover is pure KN03, despite the 
confusing label ("Stump Remover plus potassium nitrate"). I tested it 
before using it and have used it for half a year with no troubles. It 
dissolves pretty easily in water; if you have trouble try heating the 
water. I've seen some other brands mentioned specifically on The Krib as 
being pure KNO3.

As to how much, you can calculate the precise amount to add based on your 
tank's volume and the desired concentration, but most of us just experiment 
until we find the amount that works. Use the PMDD recipe as a starting 
point. I followed that when mixing my KNO3 (although I don't use PMDD 
really, I use Tropica MasterGrow and some KNO3).
