Good morning,
Been following TFP for several years and everyone in these forums has been generous with time and good advice. Last week I noticed what looked like 2 rust spots on the bottom of my pool about 1 1/2 inches long and 3/4 of an inch wide. I checked with my snorkel mask and plastic scraper and closer up, the majority of the spot looks brownish with some yellowish tinges around the edges. Scraping did nothing and I am wondering if anyone can help me identify what these spots are and what to do about them.
