"Could you share your STPP source? FReepmail me if you’d rather."

Here's where I got it on ebay:

This was the cheapest I could find online. The owner of the chemical company in Denver sold me a 50 lb bag as a personal favor, so it would be taking advantage of his generosity to send more people his way asking for it. His company isn't a retail company; it's a manufacturer.

Thanks for the link ; it’s now in my watch list. I may try it too as a comparison with TSP.
