Here is the link to the video I seen. I seen a couple of his videos and by what he says he has a background in chemicals. He seems to know what he's doing. When I purchased the bag at Ace it said nitrates. I just can't remember what kind it said it was.
But it really doesn't matter I agree I'll follow what you guys say and I'll find some real nitrates. Possibly home Depot I'll get that stump out. Thanks for setting me on the right path
