Test for high phosphate contamination (explained above) and it if it high, treat that first. Some good old elbow grease (with a wire brush) and some time in the pool will take care of an isolated spot or two, provided the water quality is right. Vacuum the mold and clean it from the filter immediately, once it is removed.

If it is too late, and your pool is covered in spots, we recommend using at least 2 pounds (per 10,000 gallons) of an algae destroyer. This is also known as granulated tri-chlor. Make sure to follow the directions on the container. It should sit, undisturbed, on the bottom for at least 24 hours.

We can perform all of these tasks for you, and we also sell and deliver the products used. It is usually worth it to pay the additional labor for us to perform the treatment, although it is not required. Contact us for prices and help identifying any of these problems.
