RE: [AGA Member] Potassium

Potassium sulphate should be fairly white if pure but its quite common
for the agricultural grade to contain some black specks or impurities.
It still works just fine. I don't know what the impurities are; perhaps
it says on the box. I can't examine mine at the moment. Anyone know?
