Phosphates Demystified: A Conversation with Terry Arko

In this episode, I’m joined again by Terry Arko from HASA to tackle a big topic in pool chemistry — phosphates. We talk about what phosphates are, how they get into your pool, and whether they’re really the enemy everyone says they are. Terry breaks down the science behind phosphates, algae growth, and why managing your sanitizer level is still the most important piece of the puzzle. We also clear up a few myths about phosphate removers and when you actually need them. If you’ve ever wondered why your pool keeps turning green even when your chlorine looks good — this episode will clear things up.
