There is algae in my pool, and my filter is not cleaning it. Why?

Your sand filter will not clean live algae. The pool water will need to be shocked or flocked to bring algae to the pool bottom to be vacuumed up. Ensure that you follow the flock chemical manufacturer’s directions on the container.
