Can you expand on the technical explanation? I know I need the AMS because we have hard water. With glyphosate and other herbicides being weak acids, you have to change the pH of the water to keep the herbicide from bonding with the water. If these other products and their additives didn't help somehow, I'm curious why they even exist. I realize more people probably don't NEED the "fancy" stuff, but it's what they had, and $20 over 2ish seasons isn't a worrisome cost.
