Black algae in a pool is not something that should be taken lightly. Although the black algae itself does not cause disease, it may attract certain insects or harbour harmful bacteria or microorganisms such as E. coli, that can make swimmers ill. It is best to avoid swimming in a pool with black algae until you have eradicated it. Below are some of the most common ways in which black algae in pool can be treated.

Black Algae in a Pool

If you or your friends have noticed black algae forming on the poolside, chances are it was caused by rain or a large rainstorm that hit your area a few hours ago. Water from rainfall expands, carrying with it dirt and debris which settles onto the ground and then becomes consumed by the roots of the plants below. While some of this debris can be cleaned up fairly quickly, a lot of it will need to be removed from your pool if you want to avoid any kind of long term damage to your pool.

Black Algae in a Pool – Can it Be Treated? 

This is a question many people ask when they are faced with the sight of a growing mass of algae in their pools. The answer is yes and no. While it is possible to treat and remove the algae from a pool on your own, there are also times when professional treatment may be required.

What Causes Black Algae in a Pool?

Before we answer that question, let’s take a look at exactly what causes black algae in a pool to form. As the water begins to draw down below the surface, and sunlight hits the water’s surface, the life cycle for certain types of algae is interrupted. 

When this happens, the sunlight is absorbed and the nutrients that the algae use to grow are suddenly not available. This means that the population of that particular type of algae will deplete, and it begins to form into a black mass. Because there are several different reasons why this occurs, it is important to know the most common causes and how these chemicals can be used to combat them.

Letting it grow and fester is the surest path to the eventual failure of your structure.
