Hello, I had posted a while back about there being some rust on a new railing. I noticed today there are a few spots of rust on my new fiberglass pool stairs, also on the stairs that aren’t even close to the rail. Is rust really to be expected for a new fiberglass pool? It is a Thursday pool. My chemistries are fine except I haven’t gotten the total alkalinity down to where it needs to be yet (150). The pool did sit filled for over two months prior to the filter and plumbing being hooked up so the chemistry at that time would not have been good. Help! I can scrub the rust off but I’m afraid of this being a recurring problem.
