Episode Details

Your pool can test high on free chlorine and still turn green. 

This episode walks through the full life cycle of a pool algae bloom, how it stays dormant for weeks, why it seems to appear overnight, and what actually happens at the cellular level when it dies. 

We cover all four types you'll actually run into, green, mustard, black, and pink slime, plus the real chemistry behind the cyanuric acid to chlorine ratio that determines whether a bloom takes hold in the first place. 

Then we get into pool algaecide itself: what's actually in the bottle (quats, polyquats, copper), how each one works, and an honest answer to a question the industry rarely explains clearly, does algaecide actually work, or is it solving a problem correct chlorine already solves on its own.
