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).
