Trying to figure out some maybe rust spots.

So I have had my pool dialed in for a couple months since finding this website. So about 3 weeks ago I had the two cracks repaired (some of you already know that story). fast forward to 4 days ago and while brushing the typical dirt of my ledges (I dont have grass yet from new home construction) some of the "dirt" would not brush off. I jumped in the pool to see what was up and it appears that its small rust spots. Its all over the two areas that were repaired including on the top edge of my pool that doesnt have water and on my concrete.

i know the dust from grinding was thrown all over those general areas and not cleaned up very well. My first assumption is that the grinding wheel used had metal in its composition and was thrown everywhere and has started reacting with the water from my pool and the rain.

does anyone have any ideas on what this could be?

Good to meet you via TFP

Check out this article... Stains in Your Pool

You can try the Vitamin C in a sock method to determine whether or not the marks are iron. You can use the same method to remove all the iron stains, if that's practical. I suspect the total amount of iron won't be enough to cause chronic staining, or require the larger iron treatment and/or maintenance.

If that doesn't lift the stains, you can try some of the other things mentioned, especially a trichlor puck. If you have a trichlor puck, I'd try that first just to rule out organic. If it's organic, just brush the spots a few times a few hours apart and normal chlorination will get them.
