How To Get Rid Of These Well Water Stains

We have a 6 year old, 35,000 gallon, plaster, in-ground pool. This pool has been so easy to maintain with zero issues until about two years ago when we noticed a few yellowish/rusty colored circular marks by the steps of our pool. Our pool co. ruled out mustard algae (or any algae for that matter) noted that all ph, chlorine, etc. levels were great and came to the conclusion that it is due to our well water. They treated with Jack's Magic Black Stuff, and that seemed to hold it at bay...at least for the first season.

Fast forward to this season...it grew from the step area and appears to be moving outward in the pool. There is no powder residue and hardly any pitting (you can't really feel anything when you rub your finger on it). Our pool co. just left today saying, again, it's hard water stains from our well water, while it may be unsightly, nothing to worry about. They said there is no need to empty the pool, treat with muradic acid and re-paint our pool.

We have used various stain bags and powders, brushed and scrubbed the stains and nothing seems to work.

My question...do you agree and what, if anything can we do to make this look better, if it's just cosmetic?

Thanks!
