    Keeping stains away

    So I have been going down the rabbit hole to remove and keep away the iron stains. So many questions and clarifications I want details on but for now let’s stick to this one thing at a time. I have treated my pool with ascorbic acid and it lifted the iron stains. Now all the Fe3+ is soluble...

    What is the best sequesterant to use after AA treatment?

    We closed our pool last year with some iron stains on the vinyl liner surfaces. We identified the stains as iron by using Vitamin C tablets.

    Iron stains with AA treatment - what should I consider "done"?

    Iron stains with AA treatment - what should I consider "done"? I have some iron stains in my pool. I got a filter setup for fill water that should take out ferric iron. I don't think it'll affect ferrous iron, but regardless, I want to try it out. So I'm doing an AA treatment, then will...

    Using Metal Magic without AA

    Has anyone used Metal Magic without doing an AA treatment first? Was it successful? MM claims that it will remove stains from the surface as well as sequester them so I’m wondering if AA is necessary. I’ve attached a pic of my 20k gal iron stained pool.

    AA Treatment - In Ground Pool - Water Exchange / Replacement

    For the past few years I've tried the AA treatment to remove my brown stains around my pool. They are most prominent on 1) Steps 2) jet output areas on wall 3) shallow end and 4) where the wall meets the floor. The deep end floor has little staining. The AA treatment always works in removing...

    My plan for iron stains

    I keep getting iron stains. Spot treatment with Ascorbic acid takes them off, then they redeposit. Rather than sequestering every week, I’m thinking of just using my pool water to water my lawn (which I need to do anyway), and refilling my pool with fresh water, thus exchanging a few hundred...
