I searched the other posts... But I'm sure this is a repeat so I apologize.

I have yellow staining around my stairs and in my skimmer. See pics

I recently upgraded to an in-ground saltwater pool. I had my above ground looking really good with the help of this forum.

pH and chlorine are on point..


I also search this form for other posts with no luck. But I'm on my phone and gave up pretty quickly.

Welcome to the forum!
Looks like iron. For the pool surfaces, take some vitamin C tablets, put them in a thin sock, crush them up, and put them against the stain. I assume they are below the water line.

For the basket, put some vitamin C tablets in a bucket of water. Let them dissolve. Put the basket in the water.

I suggest you read ABC's of Pool Water Chemistry.
