So this strange rust spot appeared on the side of my pool, unlike the other rust spot I have on the opposite side of the pool where my landscapers dropped a piece of wire into my pool and didn't reterive it there's no metal around this one. I've brushed it several times but nothing.
Any ideas on what this is and how to get rid of it? I will be draining this fall and acid washing while empty so hopefully if I can't do anything with it now that will remove it.
I've attached pictures for review. Thanks!
