Pool Algaecides

Algaecides are specialty pool chemicals designed to prevent and treat algae growth. While chlorine handles everyday sanitation, algaecides are your go-to defense when algae starts creeping in—or before it gets the chance.

Why It Matters

Even with balanced chlorine, algae can bloom after heavy rain, high heat, or poor circulation. Algaecides provide added protection and are especially helpful for stopping recurring problems like mustard or black algae.

When to Use Algaecide

  • As a preventative, part of weekly maintenance.

  • After heavy pool use, storms, or pollen surges.

  • During early signs of algae (green tinge, slippery walls).

Types of Algaecide

  • Copper-Based – Strong and long-lasting, good for stubborn algae. May stain if overused.

  • Non-Metallic (Polyquat) – Safe for routine use, non-staining, non-foaming.

  • Specialty Blends – Designed for mustard, black, or multi-type algae treatment.

Tips for Using Algaecide

Algaecide should not replace chlorine. Always brush your pool before treatment and ensure the pump runs after application. Follow dosage directions closely.

Takeaways

  • Algaecide is a backup sanitizer—not a replacement for chlorine.

  • Use weekly or at the first signs of algae.

  • Choose the right type for your pool and algae type.
