I noticed what look like small rust stains on my pebble pool surface a few months ago. There's about a dozen of them that I can see around the pool - most of them are on the tanning ledge. I just took over the maintenance of my pool about 3 months ago so I cannot speak to what my former pool service was using to manage the pool chemistry. Prior to getting my TF Pro test kit I have about 2 months worth of tests from Leslie's all showing 0 levels of iron and copper. There's never been any issue with algae in the pool or if there was my pool service did not disclose it to me. The pool is currently crystal clear and looks as good as it ever has. I replaced all of the DE filter grids 2 months ago and the filter pressure has gone up maybe 1 psi with no change in weeks.
I heard vitamin C would remove rust and have tried it 2 or 3 times and unfortunately this did not remove the stains. I looked at the bottle today and it's orange flavor chewable tabs if that matters. Any help appreciated. Thank you.
