    Keep in mind, we haven't established that any of those spots ARE black algae. The most definitive test is to scrape some off with your fingernail, and smear it on a white card: black algae will smear dark green.

    Brushing will make plaster wear through spots WORSE!

    But, if you DO have black algae, a brush like this
    Pentair R111616 604A Algae Brush with SS Bristles, 6-Inch
    will help.



    NOTE TO OTHER READERS: Do *NOT* use a metal bristle brush on fiberglass or vinyl pools, EVER!
