Hello TFPers, I am an architect working in Los Angeles on a new single family residence with a 35,000 gallon pool being planned. Our client wants to know what is the current "cadillac" of pool water sanitation systems? I am quite familiar with SWG systems but I am not sure what the most advanced treatment system currently is. Cost is not the primary concern, quality is. Is the current "best" system a UV system? I have done some initial research and this seems promising but I do not have direct experience with those systems. Any advice and recommendations are appreciated. Thanks in advance.
