How does one test for metals like iron and copper if the pool guy's test keeps showing 0ppm?
(I have a previous post titled "First Timer needs guidance" and am dealing with those issues.)
But I'm starting a new one because I believe I have a metal issue since my pool equipment is now more stained with a rust-brown color.
I don't just want to add chemicals like Metal-Out without knowing prior and I haven't found detailed info discussing metals.
Thank you all. We can't make it without you.

If you have stains, try holding a vitamin C tablet up to the stain for 30 seconds. If the stain disappears in that spot then it is most likely a metal stain.
