Algae

Algae can turn a clear pool into a frustrating mess fast-but the right response starts with understanding what you are actually looking at.

The Pool Owner's Field Guide: Algae gives homeowners a practical, poolside reference for identifying, treating, and preventing the most common algae problems without relying on guesswork or blindly adding more chemicals.

Drawing on real-world pool service experience, Billy VanVorst explains how to recognize green, mustard, and black algae, why outbreaks happen, what makes each type different, and how brushing, circulation, filtration, sanitation, and cleaning work together during treatment.

Inside, you will learn how to:

• Recognize green, mustard, and black algae
• Distinguish algae from pollen, metals, and other look-alike problems
• Follow a repeatable treatment process
• Understand why brushing and filtration matter
• Prevent algae from returning
• Avoid common treatment mistakes
• Know when a problem has moved beyond normal homeowner maintenance

Clear, practical, and designed for real pool owners, this guide focuses on helping you understand the problem, take the right next step, and know when it is time to call a professional.

You do not need to know everything about pools. You need to understand yours.
