    Algae?

    I apologize for not responding with an update sooner. The crushed vitamin C tablets in a sock made a marked difference in the rust stain and we had the company that did the replastering ten years ago inspect the surface. The result was pool surface is fine. Appreciate all of your help as always.

    Clorox

    Two weeks ago, I purchased several 3 - 1 gallon packs of Clorox 8.25% bleach(on the carton) for 9.99 at Costco. One of the jugs was actually 6.0%, thought they had just made a mistake. Went to a different Costco today and all they had were 3 - 1 gallon packs that said 6.0% for the same 9.99...

    PH adjustment not working

    Ok, here are the numbers today and the CSI tells me there is potential to be corrosive to plaster but based on the previous threads I will ignore that(unless directed otherwise) Pool water temp was 48 and I warmed the water to 72 before testing. FC - 5 CC - 0 PH -7.4 TA - 70 CH - 275 CYA - 30
