The Applied Biochemist Black Algaetrine algaecide is a powerful solution designed to combat tough black algae in pools. This unique formulation contains copper and exclusive penetrating agents that effectively kill and prevent the growth of even the most deeply-rooted algae cells.

One of the standout features of this algaecide is its ability to allow for swimming without waiting. Users can enjoy their pool immediately after applying the product, making it convenient and hassle-free. Additionally, when used as directed, the Black Algaetrine algaecide will not discolor the water, ensuring a crystal-clear pool experience.

This algaecide is suitable for a wide range of pool types, including vinyl, plaster, colored, and fiberglass pools. Its versatility makes it a reliable choice for pool owners with different pool surfaces.

The Black Algaetrine algaecide is suitable for various applications. For visible algae growth, users should apply 12 ounces of the product per 10,000 gallons of pool water. Settled algae debris can be easily removed by vacuuming. In the case of heavy algae growth, it is recommended to vacuum, clean, and scrub the walls before applying 12 ounces of the algaecide per 10,000 gallons of pool water. Vacuuming should be repeated to remove any remaining algae debris.

To maintain a pool free of visible algae, a maintenance dose of 6 ounces of the algaecide per 10,000 gallons of pool water should be applied every 5 to 7 days. It is important to note that in high temperatures or if the pool has unusually heavy use, the maintenance dose should be added more frequently.

For optimal results, it is advised to apply this algaecide in the morning on warm, sunny days. Due to black algae's tough, waxy coat, using an algaecide specifically formulated for black algae, such as the Black Algaetrine algaecide, is crucial.

The Applied Biochemist Black Algaetrine algaecide is compatible with chlorine, bromine, and ozone sanitizers, making it suitable for use with different pool maintenance systems.

With a combination of algaecides specially formulated for black algae and 3.07% active copper content, this algaecide offers excellent performance and reliability in fighting and preventing black algae growth in pools.
