I am having a problem killing some annoying Black Algae that has started to grow in my pool.
I have looked at many sites and they provide some useful information for concrete, plaster and other non-vinyl lined pools. Many of the suggestions involve scrubbing with a wire brush and pouring chlorine directly onto the effected areas. Of course, these solutions will not work with vinyl.
My pool is an in ground 12x28, vinyl-lined pool. All of my chemical levels are in balance and the water is clear. My only issue is the stubborn Black Algae that keeps coming back.
I have tried a copper based algaecide and super chlorinating with lots of scrubbing and vacuuming. This works for a day or over night and then it is right back where it was, so I start all over again. I have been using this process for about two weeks now and the stuff goes away and then comes right back.
Any help that you can give me would be appreciated.
