In this episode, I sit down with Terry Arko from HASA to dive deep into one of the toughest pool problems out there — chlorine-resistant algae , including the dreaded black algae that laughs at your shock treatments. We talk about why some algae survive even in well-maintained pools, how biofilms protect them, and what steps actually work to beat them for good. Terry shares his expert insight from decades in the field, breaking down the myths and science behind stubborn algae blooms. If you’ve ever felt like your chlorine isn’t doing its job, this one’s a must-listen. Send us a text Support the Pool Guy Podcast Show Sponsors! HASA https://bit.ly/HASA The Bottom Feeder.
