How to get rid of blackspot algae in your swimming pool
Understand black algae.
Like any alga species, black algae (which are really blue-green algae that look black) will grow quickly in warm water on a sunny day. Black algae are chlorine-resistant, because they have a protective outer layer that makes regular sanitization ineffective.

OPTIONS:
- Try a plastic or glass aquarium pump to see if you can get rid of the mildew. Plastic pumps don't scratch or dry algae scales, making them great for water-decontamination, while glass pumps may not.
- While algae aren't harmful, their presence can be a sign that other bacteria are present. Other alga species that are common in pools are green algae, mustard or yellow algae, and pink algae, which is actually a bacterium.
- No matter the weather, a change in water temperature is advisable. Because of this, you should still be cautious when swimming in a pool with black algae.
- Black algae can also grow up in clumps on your pool floor and around corners, which can aggravate the entire problem. Remove black algae by using a commercial water purification spray.

While algae aren't harmful, their presence can be a sign that other bacteria are present. Other alga species that are common in pools are green algae, mustard or yellow algae, and pink algae, which is actually a bacterium.
