I don't have an online source for STPP. I buy it in 50 lb sacks from my local chemical supply outfit. I keep the sack in a plastic bin to help prevent deterioration from exposure to atmospheric moisture (STPP gradually decomposes to a less effective form, TSP, upon prolonged exposure to moisture/heat).
STPP and hard water go together like Bob and big loads.
