Applied Biochemists Black Algaetrine is a unique, patented blend of algaecides specially formulated to control black algae and other equally resistant strains. Its powerful formula easily penetrates the thick, waxy coating black algae uses for protection, quickly killing it all the way down to its roots, yet contains only 3.07% active copper to avoid any need for water rebalancing. Best of all, Black Algaetrine is made by Applied Biochemists, a leader in bio-based pool chemicals, allowing you to buy with confidence.


If Black Algae is present, use 12 fl oz per 10,000 gallons of water.

  1. Dilute in a bucket with at least nine parts of water before applying.
  2. To remove black deposits: Brush areas vigorously with a stiff or special algae brush immediately prior to application. This will help break up the black algae colonies that have formed.
  3. Apply Black Algaetrine (12 oz. per 10,000 gallons).
  4. Brush again once each day for two days following application. Remove any settle algae by vacuuming. Reapply treatment if necessary.
