I'm just hearing conflicting things and the technical evidence in this thread supports a lower CYA....especially for SWG systems.

I understand a high CYA can extend the Cell life because you can maintain a lower chlorine ppm at a lower setting, but does that really mean a healthier pool?

You use whatever setting YOUR pool needs to be healthy. It will depend on bather load, weather, and any other kind of upsets. The lower the setting you can use on the pool the better.

Would it be incorrect to say that a SWG system running at 0 CYA and 1ppm chlorine 24/7 is the most effective? (Not taking cell life into account).

Yes it would be incorrect. Please reread what I said in my post above. You need the CYA ppm for the reasons stated.

I dont want to contradict this forum, perhaps a new thread in the "china shop" is more appropriate?
Hope this helps.
