    The Three Culprits: Green, Yellow, and Black Algae:

    1. Green Algae:

    Description: Green algae are the most common type found in pools. They typically appear as green, slimy patches or streaks on pool surfaces.

    Characteristics:

    • Thrive in the presence of sunlight.
    • Quick to spread.

    Removal: Use algaecides and proper pool maintenance to treat green algae.

    2. Yellow Algae (Mustard Algae):

    Description: Yellow algae appear as a fine, powdery substance settling on pool walls, steps, and other surfaces. They may also look like yellowish patches.

    Characteristics:

    • Resistant to chlorine.
    • Can be challenging to eliminate.

    Removal: Specialized algaecides and scrubbing are needed to eliminate yellow algae.

    3. Black Algae:

    Description: Black algae typically appear as dark, black or blue-green spots with a unique appearance. They often have protective layers and root-like structures that attach to pool surfaces.

    Characteristics:

    • The most challenging to eliminate.
    • Have a protective layer that shields them from regular pool chemicals.

    Removal: Removing black algae requires intensive scrubbing, strong algaecides, and sometimes even draining and acid-washing the pool.

    • Regularly test and balance your pool water.
    • Maintain proper sanitizer levels.
    • Keep pool surfaces and equipment clean.
    • Use pool covers to reduce sunlight exposure.
