How to Get Rid of Black Algae

Follow these steps to get rid of black algae so your family can enjoy your pool.

Algae in pools is a problem for many residential pool owners.  Black algae in the pool is particularly difficult to treat because black algae cells have a hard outer shell that protects them from algae control efforts.  After you get rid of black algae in the pool, it is important to implement a regular algae control program so you can avoid future problems.  The following steps from PoolGear Plus offer the most effective method to quickly get rid of black algae and then help prevent it from coming back.  

Step One: Adjust the pool water pH to a range of 7.4-7.6 and the alkalinity to a range of 80-120ppm.  

Step Two: Brush all black algae spots with a nylon brush if your pool is vinyl, fiberglass, or painted, or with a wire algae brush for all other pool types.  

Step Three: Add 1.5 quarts of Metal Control per 10,000 gallons of pool water.  Metal control softens the hard outer shell that protects black algae cells. 

Step Four: Mix Super Black Algaecide into a bucket of water and pour it in the pool away from the sides of this pool.  Super Black Algaecide is a fast-acting concentrated algaecide specifically formulated to kill black algae.  Use 12 ounces of this algaecide per 10,000 gallons of pool water.      

Step Five: Brush black algae spots daily while the algae is visible.  For severe cases, call 888-718-7946 to consult with a Pool Care Expert.  You may need to repeat the algae control process or double the algaecide dosage to get rid of all of the black algae in your pool.  

How to Prevent Black Algae

To avoid the expense and effort required to get rid of black algae, as well as the downtime required while you treat your pool with algaecide, it’s best to prevent black algae from growing in your pool in the first place.  To do this, follow the label directions for algae prevention on our All in One Algaecide.  This is our best multi-purpose algaecide; it keeps your pool algae-free without foaming and contains a clarifier property to keep your water sparkling.  Algaecide should be used on a weekly basis as part of your regular pool maintenance program.
