Description

AlgaeShield 12771 makes algae control simple and reliable. Its copper‑based formulation remains active for weeks, so monthly maintenance keeps algae at bay.

Designed to reduce manual labor and let you spend less time scrubbing and more time enjoying your pool.

Pro Tip

Brush pool surfaces before applying AlgaeShield. After treatment, run filtration 24‑48 hours to clear dead algae. Use a clarifier or booster to help remove fine particles faster.
