Just joined the TFP family after reading many threads for months. I'm just in the design phase of my new approx 50K gallon pool in sunny Southern California. The pool will be in full sun with only partial late afternoon shade. My family has a fair amount of parties and I anticipate heavy bather loads during all major holidays including lots of kids. Given the higher chances of "accidents", I need to be certain that no one will get sick while using our pool. Now before you chop off my head... I know many of you favor your tried and true method, but there has to be a reason Europe banned CYA and commercial pools limit it to
This has led to me searching for the best filtration/sanitation equipment. AFM NG? AOP? Dryden Daisy? SWG? Cal-Hypo? ChlorKing NexGen?
I'm familiar with the AutoPilot - Pool Pilot total control system that I've set up on my Grandmother's pool many years ago. I'm certainly not opposed to a Salt pool, one of my questions is Pool Pilot recommends "Pools using an ORP Controller (Oxidation Reduction Potential) such as the AutoPilot Total Control, should maintain 30-50 ppm." But I see on your TFP Chlorine/CYA chart the min CYA recommendation is 70 ppm?
I've also read an article on CYA effects on disinfection which I'm certain you can search and find. But 2 bullet points are:
Dryden says using a product like APF removes phosphates that Algae & Bacteria need for growth thus preventing these from becoming an issue.
Why would anyone want to maintain higher levels of CYA/Chlorine? Aren't you swimming in a less safe pool? Sanitation is greatly reduced the higher the CYA levels get right?
Now before you chop off my head... I know many of you favor your tried and true method, but there has to be a reason Europe banned CYA and "While the CDC's recommended limit is 15 ppm for a commercial pool, the ideal sunlight protection is around 30 ppm... the vast majority of chlorine is already protected at 30 ppm."
Is there really a benefit to CYA over 30ppm?
Now if I can speak to filtration, has anyone used Dryden AFM NG? This glass media filters down to 1 micron & never needs replacing. My pool designer tells me that all of his commercial accounts have switched to it including some major So Cal water parks and Vegas casinos due to it's lower micron filtration and 50% less backwash water needed. Just interested in personal experience using this product.
Thanks guys for your feedback & personal experience with using any of the above mentioned products.

- Using this 14:1 CYA to FAC ratio, the maximum CYA concentration should be 14 ppm for a minimum chlorine concentration of 1ppm or 28 ppm for a minimum chlorine concentration of 2 ppm.
- Considering the EPA limits of 1-4 ppm free chlorine, we recommend that CYA concentrations be kept below 14 for all chlorine levels to ensure adequate bather safety
