10:50 Black Algae. It is a Cyano-bacteria that exists in natural freshwater sources. Birds, ducks, or other animals or insects can transfer it to your pool. It can also be transferred to your pool by swimming suits worn in a lake and then worn in your pool. How and why is it getting in your pool? Lack of maintenance, adequate sanitizer levels, or circulation can prevent black algae.

Black algae have a bio-film protective layer that has to be penetrated before you can kill the cyano-bacteria.

Brushing or pressure washing is necessary to penetrate the protective bio film.

scrubbing black algae spots with a chlorine tab is a good way to penetrate the biofilm, and applying concentrated chlorine directly onto the cyano-bacteria.

BlueRay XL is a mineral purification system that works very wel in, preventing, controlling,g and helps to eliminateg black algae.

Many black algaecides have high concentrations of metals. If not monitored and controlled metals can stain your pool surfaces.

Culator metal eliminator is the only way I have found to remove metals from pool water effectively. Many "metal control" products only sequester metals. Chlorine breaks down sequestering agents. They are a temporary help, but do not remove the metals from the water.

If you have metal stains on your pool surfaces, the stain has to be pulled back into the water before you can remove it.
