I have an 18x36 saltwater pool...opened in May and added typical chemicals, salt, and shocked....What I didn't do was clean out the bottom of the pool for a few weeks....When I did get around to vacuuming the leaves and worms out after I finished I noticed most of the pool surface that didn't have leaves or worms had a brownish/yellow stain....In the days that followed my chlorine level dropped to zero several times and I rechlorinated with shock....After consulting my pool guy we came to the conclusion that it was some sort of Algae, so I have super chlorinated and used black mold algecide twice and still I can't get rid of the stains....I also have noticed a cobweb or thin hair substance in the skimmer after cleaning...I am looking for some adivice...I know I can add more algecide and continue to chlorinate at high levels, but I'm wondering if I need to try "Stain Free" or "Metal Free" to see what they will do...
Thanks,
