Pool Pros text questions here Got mystery stains, teal-tinted water, or customers blaming your chlorine for their new “seafoam highlights”? Andrea and Paulette dive into high metal levels in pools—where they come from (source water, corrosion, “helpful” copper products), how to confirm what you’re dealing with (iron vs. copper vs. manganese), and the smartest ways to treat the water and the stain without turning the pool into a chemistry crime scene. Real talk, step-by-step protocols, and the dos/don’ts that save callbacks. Chapter Markers 00:00 – Cold Open: “No, chlorine didn’t dye your hair green.” 02:10 – Metal 101: Iron, copper, manganese—how they look, act, and stain 07:45 – Where They Come From: Source water, heaters, low-pH corrosion, old copper algaecides 12:30 – Testing That Doesn’t Lie: Spot tests, stain ID, metal test kits, source-water pulls 16:20 – Immediate Triage: When water is tinted vs. when you have bonded stains 20:15 – Stain-Lift Playbook: Ascorbic/citric protocols that actually work 25:50 – Sequestrants & Chelants: HEDP/ATMP, maintenance dosing, timing with chlorine 30:10 – Actual Removal: Partial drain/replace, prefilters, metal capture media, poly-fill hacks 34:30 – Prevention Clinic: LSI balance, anodes, heater protection, product choices 39:00 – Rapid-Fire Q&A & Takeaways Key Symptoms & What They Usually Mean Brown/tea stains or yellowing: Often iron; may cloud when pH rises or after superchlorination Turquoise/black smudges; blonde hair turning green: Usually copper; often tied to low pH/heater corrosion or copper algaecides Black/grey/purple blotches: Possible manganese; shows up in well water regions Testing & Identification (Fast & Reliable) Pull a source-water sample (hose bib before softener) to see what you’re adding every fill/top-off. Use metal test kits (iron/copper/manganese) and stain ID tests (vitamin C for iron, etc.). Verify pH & LSI first—metals love to fall out when pH/alk/CH swing. If a heater is present and copper is high, inspect for low pH corrosion and flow/erosion issues. Support the show Thank you so much for listening!
