Round "RUST spots" popping up everywhere. Can't remove with brush or scraper.
Hi there,
I've finally gotten a handle on my pool chemistry but now these little reddish brown circles have started popping up all over the pool. They are about 1/8in diameter, and I can't vaccum, brush, scrube, or scrape them off.
They seem to be multiplying. I have a fiberglass pool, so I doubt they are rust.
Any ideas?
