The Three Main Types Of Pool Algae And How To Remove Them

Posted on

Pool algae is a common problem, that can occur for a wide variety of reasons, such as a damaged filter, improper balance of chemicals in the pool water, or even just excessive sunlight exposure. There are several different types of algae that can begin to grow in your pool, each of which requires a different method of elimination in order to restore the cleanliness of your pool. Understanding the differences between the various types of algae that can take root in your pool can help you eliminate algae growth early before it becomes a serious problem.

Green Algae

Green algae is probably the most common type of algae that can take hold in your pool, and has a slimy feel to it. Green algae will begin to grow due to a lack of chlorine in your pool, and will most commonly begin to grow in the corners and crevices of your pool, especially on the steps and around the vents. In order to eliminate it, you need to apply shock treatment to your pool's water: the higher levels of chlorine and sanitizing chemicals will rapidly kill the algae, which can then be scrubbed off of the walls and steps of your pool as needed.

Black Algae

Black algae, despite its name, can also take on a dark green or dark blue hue. Unlike green algae, black algae is hard to the tough, not slimy. This hard surface protects black algae from high levels of chlorine and other chemicals in your pool's water, which makes black algae a real pain to clean up. In order to remove it, you'll need to make use of a stiff or even steel bristled brush to break through the hard shell of the algae.

Pink Algae

Though not as common as either black or green algae, pink algae can take hold on plastic materials within pools. Pink algae is actually fairly simple to take care of, as it does not have the hard exterior of black algae and can't resist against even moderate levels of chlorine and other chemicals. If you see any sort of pink algae taking root on the plastic components of your pool, you can simply make use of any sort of brush or rag to remove it. If pink algae is widespread throughout your pool, your pool water is likely almost devoid of any sort of chlorine, so you should check your chlorine levels and add more as necessary – even a moderate amount should be more than enough to remove your entire pink algae problem.
