Key Takeaways
- Identify before you treat. Color + texture + location + “does it brush off?” beats guessing.
- Sanitizer effectiveness is conditional. As CYA rises, the % of active hypochlorous acid drops; dose and contact time must adjust.
- Mechanical + chemical wins. Aggressive brushing and good circulation expose biofilms so oxidizers can work.
- Mustard/yellow needs elevated FC (and whole-pool exposure for toys, nets, lights, covers).
- Black “algae” is cyanobacteria anchored in porous surfaces; expect repeated disruption and sustained levels—not a one-and-done.
- Filters tell the truth. Restore flow, deep-clean media, and fix bypass/broken laterals or you’ll chase the same bloom.
- Phosphate control is situational. It can lower regrowth pressure but doesn’t replace sanitizer.
- Borates steady pH and deter slime, but they’re not an algaecide.
Episode Summary
Andrea and Paulette go long on algae—the real science, the field diagnostics, and the no-nonsense remediation that actually works on a Tuesday in August when the phone won’t stop ringing. Pulling from training content and field notes, they break down how to tell algae from look-alikes (metals, pollen, fine dust), why water balance and sanitizer demand dictate outcomes, and how to choose the right kill-sequence for mustard/yellow, black (cyanobacteria biofilm), green blooms, and stubborn pink slime/white water mold co-contaminations.
They also reference Rudy Stankowitz’s book, How to Get Rid of Swimming Pool Algae (Amazon), for deeper reading on species behavior, biofilms, and step-by-step playbooks that complement today’s talk.
