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.
