Yellow / Mustard Algae
Yellow or mustard algae is particularly common in swimming pools in the southern part of the US. It is most often seen as patches of dark yellow dust that covers various parts of the pool walls and floor. Mustard algae usually starts in the corners of the pool, near the steps, behind the ladder, and in other areas where the water circulation is poor.
Unless yellow algae gets into the cracks, pits, or crevices of the pool surface, it will brush off easily. Follow brushing with pool shock, then a treatment dose of algaecide formulated to treat yellow / mustard algae.
As always, follow label directions and pool chemical safety guidelines when treating algae in your pool. And remember, using algaecide weekly in a preventative dose will keep your pool clear and sparkling.
