Well, after cleaning up all the algae all summer last year, going through hundreds of $$ of bleach, we saw the vinyl was pretty much covered in gray/green stains. I've stayed on top of tall the chemicals, and then waited until this Spring and just did the Jack's Magic Stain Identifier. It turns out we have Iron Scale and need Solution #1 and #2. For a 44,000 gallon pool, it seems that it will cost us over $1,000 to get this all done, plus from what I understand it could take weeks. So, I guess we just keep it as is until we replace the liner? Is this really the only way to rid our pool of these stains?
