3 Common Pool Algae Types & How to Remove Them for Good!
Our expert swimming pool technicians have the right knowledge about all pool algae types, chemicals, equipment, and experience to eliminate algae buildup in your pool or spa quickly and effectively. But the best way to deal with algae? Stop it before it starts!
If your pool is algae-free you’ll want to stay proactive in keeping it that way. Prevention is key, and the first step is understanding what causes algae growth and recognizing the three main types that commonly affect pools and spas in Atlanta and beyond. Let’s dive in and keep your pool crystal clear!
Understanding Why and How Pool Algae Types Grow
During the summer months (typically July and August), algae usually become a real problem for swimming pool owners everywhere. The reason for this is a combination of your pool's high summer temperatures and lower sanitization levels—a problem only seen with owners who fail to have the proper swimming pool cleaning plan. Algae are a single-celled plant form that harnesses sunlight to create its food source, which we know as photosynthesis. This allows it to flourish inside your pools and spas during summer, with extended hours of sunlight hitting the water.

1. Black Algae
While most pool owners refer to this type of algae as black algae, it is, in reality, known as blue-green algae. This algae typically grows in cracks and crevices of the swimming pool's surface. It is especially fond of plaster and concrete finished pools due to its rough surfaces. Visually, black algae are known for their slimy appearance, which usually forms in a skeletal pattern along your pool's surface, making it immune to standard chlorine levels.
While black algae typically do not adversely affect your water clarity or safety, they will leave unsightly black spots on your pool's surface, and most pool owners want to run for the chlorine to get rid of them.
How Do our Professionals Get Rid Of Black Algae?
To effectively treat pools dealing with black algae growth, our swimming pool cleaning professional will typically opt first to analyze and balance your pool water. Next, before the removal of black algae can occur, our pool professional will thoroughly brush the algae from your pool's surface to break through the slime layer. After that, they will aggressively shock the pool and touch it again until the black algae are entirely removed.
2. Green Algae
The most common type of algae pool owners face the aptly-named green algae, which can turn your pool water green. And unless you're celebrating St. Patrick's Day, that can make for a pretty disgusting swim. Despite its name, however, green algae can sometimes appear blue-green, yellow-green, and even dark green. Beyond turning your water green, green algae can also cling to the walls of your pool and leave stains on vinyl siding if not treated promptly.
How Do our Professionals Get Rid of Green Algae?
When approaching green algae removal, our swimming pool cleaning professional will first analyze your pool's water and pH levels to ensure the water is at the proper levels. Your pool will then be brushed and vacuumed thoroughly before being shocked. During this process, your technician will check the pool's filtration system to ensure the water flows correctly. This process may be repeated a few times to remove all green algae from your swimming pool.
3. Yellow (or Mustard) Algae
Mustard algae are, in fact, a mutation of green algae. Like their predecessor, they are highly resistant to normal chlorine levels, making them nearly impossible to remove if you don't have the necessary cleaning supplies. Varying from yellow-green to brown, mustard algae typically look like dirt or sand on the sides or bottom of the affected swimming pool.
To rid your pool of mustard algae, our swimming pool professional will use the same techniques to remove black algae.
