I have brownish stains on the floor and the floor edges that I cannot remove. I have a white fiberglass pool and have tried multiple stain removers (sparkle conquest, natural chemistry stain free and united chemicals super stain treat). The stains appear to be spreading to a 4 foot ledge all the way around the pool.
