Ah, AOP. The latest in the endless "don't use cheap and effective chlorine, pay us way more for the same or worse results!" sales tactics. (HINT: it's always worse)
It is a thing. It can be used as supplemental oxidation, though in a residential pool such supplemental oxidation provided by AOP or ozone is entirely unnecessary. It does not provide adequate sanitation, if any. And given that "drinkable water" from a municipal supply tends to have a higher active chlorine level than a TFPC managed pool, that seems like a step backwards, right?
