Algae are types of microscopic plants that enter pools via rain, wind, swimsuits, and pool toys. These tiny plants multiply and thrive quickly, especially when the pool is frequently used, subject to heat and sunlight, and already features vegetation. Lack of pool maintenance like regular filter changes also causes high algae levels.

Help your pool remain clean and sanitized by learning what types of algae thrive in chlorinated water and how you can eliminate them with proper pool maintenance.

Different Types of Algae

Green Algae

Green algae is the most common algae in residential pools. It floats in the water and turns it from blue to hazy green. It can also spread to your pool’s floor, walls, and stairs.

Mustard Algae

Mustard algae sticks to pool walls and is usually present in shaded areas. It’s often mistaken for dirt, pollen, or sand—however, none of these materials cling to pool walls.

Black Algae

Black algae creates dark spots on your pool’s walls and floor. Its roots make it difficult to eliminate, particularly when it’s on a rough surface like a plaster or concrete pool wall.

Keeping Your Pool Clean

Pool Cleaning Tips

Brushing your pool walls frequently with a pool brush and vacuuming the pool floor keeps algae from taking over. Shocking your pool and using the recommended amount of algaecide also helps. Set your filter to “waste” before vacuuming and brushing, as algae can thrive on pool equipment. Also, remember to rinse your bathing suits, floats, and pool toys after a beach day to avoid bringing algae into your pool.
