Chem_Geek means that "MUST" as in, the pool mavens will shake a finger at you, if you don't. Thank God, there are no residential pool inspectors in the USA -- at least once the pool is done.

You are free to swim in sweat, urine, and even poop to your heart's content, so long as you health holds out. Just don't ask me to get in with you! We try help people here make informed choices, but I believe it should still be THEIR choice, at least for themselves and their family, no matter how, uhm, 'poor' a choice it is. In fact, if you want a genuinely "natural" pool, that's fine too: I even have a photo gallery of them here! Some of them are extremely attractive, if not completely sanitary.

On the other hand, if Caribbean Clear starts claim to provide chlorine free sanitation (as they did some years ago), Chem_Geek or I or someone else is likely to report them. And the penalties for that, are real.
