Description of 1 Quart Concentrated Black Algaecide.

Black Algaecide has been specially formulated to prevent and kill the growth of black algae, but is also effective on green and mustard algae. Although black algae are known to be particularly stubborn and often resistant to standard algae removal chemicals, this is the product to turn to when no other product will work. This potent and effective formula contains no metals, so it won't stain surfaces and is non-foaming. Black Algaecide helps to clear cloudy water for a cleaner, healthier swimming environment.

60% Poly Algaecide.
