Still learning about my pool… I see what I think may be black algae. I’ve tried to use a wire brush but I can’t get it to budge. Any suggestion would be much appreciated. Thank you
The best chemical I’ve used to remove black algae is silver algaecide. You’d brush the spots lightly with a steel brush and then add the silver algaecide to the skimmer. The silver algaecide we carry is part number 403303.
