In this episode of the Pool School Podcast, Roy "Al G" Free tackles the ever-present challenge of algae growth in swimming pools. Algae, whether it's green, yellow, or black, can quickly turn your pool from a refreshing oasis into a green, slimy swamp. Roy dives into the world of metallic algaecides, specifically copper, silver, and zinc, and explains how these powerful metals work individually and synergistically to prevent and control algae blooms.

Key topics covered include:

1. What are Chelated Metals?
   Roy explains the process of chelation, which involves binding metal ions to molecules to keep them stable and effective in the pool. Chelation ensures that the algaecides remain active longer and reduces the risk of staining pool surfaces.
2. Copper: The Algae Killer
   Learn how copper works to kill algae by causing cell lysis, breaking apart algae cell membranes. Roy also discusses how copper disrupts the Calvin cycle, a crucial part of algae's photosynthesis process, preventing them from producing the energy they need to survive.
3. Silver: The Stealthy Biocide
   Roy delves into silver’s unique method of causing oxidative stress inside algae cells, damaging their internal structures and ultimately leading to cell death. Silver’s ability to weaken algae internally makes it an effective and silent killer.
4. Zinc: The Supportive Player
   Zinc's role is more subtle but no less important. Roy explains how zinc affects algae's ability to metabolize energy and photosynthesize, weakening them and making them more vulnerable to copper and silver.
5. Synergy of Copper, Silver, and Zinc
   When combined, these three metals create a powerhouse algaecide. Roy explains how they work together, each targeting different aspects of algae biology, ensuring a more comprehensive and long-lasting algae control solution.

By the end of the episode, listeners will understand how these metallic algaecides work, why chelation is crucial for their effectiveness, and how to use them together to keep pools clear and algae-free. Whether you're a pool owner or a professional, this episode offers practical insights into using copper, silver, and zinc for algae control.

Key Takeaways:

• Copper, silver, and zinc work together to attack algae on multiple fronts.
• Chelation helps metallic algaecides remain effective for longer without staining.
• By understanding the science behind these metals, pool owners can make smarter decisions to maintain clean, clear water.
