Common Types of Pool Algae

Algae formation is a common concern for pool owners, and without proper chemical care, your swimming pool can play host to several different types of algae. Algae can appear and spread quickly, particularly in the summer months, and if not treated swiftly can be difficult to eliminate. As a Valley leader for over 47 years, we understand the importance of proper pool care and maintenance. If you have started noticing algae forming in your pool, don’t delay in seeking a solution. Read on to see the most common types of algae you might see in your pool.

Green Algae

Green algae is the most common type homeowners will have to deal with, and colonies of green algae can often be found on various pool surfaces like stairs or walls or even floating, imbuing the water with a green hue. Sometimes if left for long periods untreated, these colonies can completely cover and obscure the pool so that not even the bottom or steps can be seen. While green algae is easier to treat than other forms, it can grow and spread quickly, so pool owners must be vigilant at the first sight of green algae to make sure their pool’s chemical composition is within ideal range. With proper chlorine maintenance or a professional treatment, you can ensure your pool stays free of green algae.

Yellow Algae

Yellow algae is similar to green algae but is more difficult to treat. This type of algae is commonly seen in pool areas that are shaded, and are characterized by a mustard color and slimy appearance. Yellow algae is best treated by scrubbing the affected area with a pool brush and, like with green algae, checking and monitoring the chemical levels in your pool. Though not as quick to spread as green algae, as it is more resistant to treatment it can much harder to remove.

Black Algae

Black algae is a common but significantly difficult type of algae to eradicate, as it is able to grow rapidly and often spreads underneath the surfaces of your pool making it more difficult to spot before it has already taken root. Black algae is drawn to porous surfaces like plaster, and through these porous surfaces can spread throughout the entire pool. Black algae infestations start small making it difficult for pool owners to realize their pool has it before it is too late, and by the time you notice black patches this alga has already grown significantly underneath the pool surface. Even treating the visible colonies of black algae does not ensure that all of it has been removed from your pool, so if you have begun to suspect your pool harbors black algae a professional consultation is paramount.

Pools are a great backyard amenity, and if well maintained can be enjoyed for years to come. If you start noticing your pool is having issues, don’t delay in getting help from professionals.
