The right alkalinity? I work for a pool company and we tend to keep salt pools at 150 and chlorine pools at 120 (it also gives these numbers on the bag of the pH buffer we use). So I am confused when I see people here say it doesn’t really need to be above 100. I kind of agree, since when pools have lower alkalinity the pH stays lower too, which is helpful in concrete/salt pools. Hence why I’m starting to question why we keep alkalinity so high? Is there any advantage? Or is it just so we can sell more buffer? Lol
