I use Sodium Nitrate 99%+ pure purchased it off of Amazon.com I was at one time adding a lot and didn't want to throw my potassium out of whack. Not sure about the fertilizer grade KNO3 though. Fertilizer grade is likely pretty low grade not processed or purified, who knows what else is in there. I would recommend purchasing at least food grade. The Calcium Nitrate looks interesting.
