Black algae is one of the most stubborn and damaging forms of pool algae. Unlike green or yellow algae, black algae forms deep root systems that embed into plaster and concrete surfaces, making it extremely difficult to eliminate with standard chlorine or shock treatments alone. Applied Biochemists Black Algaetrine is a professional-strength black algae killer specifically formulated to penetrate, kill, and control black algae at the root level.

This concentrated treatment is designed for corrective use when black algae is already present. Pool service professionals rely on Black Algaetrine because it delivers targeted, aggressive action without foaming or staining, making it suitable for demanding remediation situations.

Why Black Algae Requires Specialized Treatment

Black algae is resistant by nature. Its protective outer layer shields it from normal sanitizer levels, allowing it to survive repeated shocking and brushing attempts.

Proper black algae treatment matters because it helps:

• Penetrate algae roots embedded in plaster and concrete

• Prevent regrowth after surface cleaning

• Restore pool surfaces without acid washing

• Reduce long-term chemical overuse

Applied Biochemists Black Algaetrine is formulated specifically for this level of algae resistance.

How Applied Biochemists Black Algaetrine Works

Black Algaetrine uses a targeted algaecide formulation designed to break through black algae’s protective layers and attack the organism at its base. This allows the active ingredients to reach the root structure, where standard algaecides often fail.

When used alongside proper brushing and filtration, Black Algaetrine helps loosen embedded algae colonies so they can be killed, filtered, and removed from the pool system.

When to Use Applied Biochemists Black Algaetrine

Black Algaetrine is intended for corrective treatment, not routine prevention. It should be used when black algae is visibly present or confirmed, including situations such as:

• Dark, raised spots on plaster or concrete surfaces

• Algae that does not respond to shock or standard algaecides

• Recurring black algae in the same locations

• Pools with porous surfaces prone to algae root penetration

Because black algae is aggressive, treatment should be combined with brushing and proper sanitation for best results.

Compatibility with Pool Systems & Surfaces

Applied Biochemists Black Algaetrine is designed for use in traditional swimming pools and is most effective on plaster, marcite, and concrete surfaces where black algae typically embeds.

It is compatible with standard chlorine pool systems and works with cartridge, sand, and DE filters. When used as directed, it will not foam or stain pool surfaces.

Professional-Grade Corrective Algaecide

Black Algaetrine is not a mild or maintenance algaecide—it is a specialized corrective solution. Pool professionals use it when normal algae treatments fail and a more aggressive approach is required.

Because black algae remediation can take time, multiple treatments and continued brushing may be necessary depending on severity. Black Algaetrine provides the chemical strength needed to support that process.

Application & Treatment Best Practices

For best results, affected areas should be aggressively brushed prior to application to break the algae’s protective surface layer. Black Algaetrine should then be added to circulating water according to label instructions.

Continuous filtration is recommended during treatment, and dead algae should be vacuumed or filtered out as it detaches. Maintaining proper chlorine levels after treatment helps prevent regrowth.

Always follow manufacturer label directions and safety guidelines.
