    Pool staining

    Bought a house in July last year that the previous owners did not maintain, I've been trying to get rid of staining for a while now with no luck the stains are yellow brownish and some are black, tried spot out and shocking. The pool store told me try drain free acid wash with two gallons of acid. The water test is normal except the TDS are at 4400. What are my options? I have pictures I can post and we live in central Florida

    Welcome to the forum
    You must make a very organized approach. the stains didn't get their overnight so it may take a while to get them out.

    Can you post test results? (organized Like This?)

    What is the source of your refill water? How long have the stains been visible? Post your best pic of the stains.
