Without any sources cited, I struggle to take it seriously.
There's a reason no citations are listed: it's a "list" of abject lies, half-truths, and dishonest rhetoric written by a company who sells chlorine-free pool "sanitation" solutions that lead to water that is unsafe for people to be in.
"Salt water corrosion" in a pool is a myth. All pools require chemicals (and CYA is not "cyanide based".. wow). SWCG cells absolutely last longer than "2-3 years". pH is a concern in all pools. Your sweat is significantly, significantly higher sodium than the water in a SWCG-equipped pool. The water in a SWCG pool is not "brine".
The facts are very clear: the EPA lists THREE acceptable sanitizers for swimming pools. Period. Three. They are chlorine, bromine, and biguanide. Magic "minerals" do not santize your water, copper and silver do not santize your water, and UV does not sanitize your water. There is no magic bullet besides chlorine. There have been many, many, threads about this over the years and Richard Falk (@chem geek) organized a lot of this if you look through his post history, such as in this thread here, where he discusses the efficacy of sanitation methods. Long story short: you need chlorine for safe water.
