I just completed a CA treatment as I couldn’t procure AA, and have pH/Alk at 7.1 and 70, slowly adding chlorine. Made it 2 cups of liquid 12.5% and 2.5 bottles of Jacks blue in (following AA protocol to add more if stains reappear) and I’m still having slight staining starting to reform. What am I doing wrong or do I need to call the water company and have them test my water? Is there any recourse whatsoever if there is this much metal in the water since copper is considered an essential nutrient? 2018 test results posted showed .3ppm copper and I’m thinking there even more than that if I can’t sequester it.
