Applied Biochemists Algaetrine – Fast-Acting Algaecide, 1 Qt

Powerful Algae Control for Clear, Inviting Pool Water

When algae takes hold, it can quickly transform your pool from clear blue to cloudy green. Applied Biochemists Algaetrine is a fast-acting algaecide formulated to eliminate and control all common types of pool algae—including green, yellow (mustard), and stubborn black algae. This concentrated liquid is safe for all pool surfaces and won’t cause staining or foaming, making it an essential part of your pool care program.

Why Choose Algaetrine?

Not all algaecides are the same. Some stain, some foam, and many only work against limited algae types. Algaetrine is specially designed for broad-spectrum control while keeping water safe, clear, and comfortable. Its non-metallic formula works alongside chlorine or bromine systems, delivering fast results without interfering with water balance.
