This guy reminds me of the reason I found this website. My local pool gal seemed like a knowledgeable enough person to trust but when I asked the question “why can’t I hold chlorine?” she gave me the reason. “Some years pools just act differently and this year I’m seeing a large number like yours, you just have to add more chlorine and make sure your tablet feeder stays full”.
Is he ignorant in the link between CYA and chlorine or smart enough not to let people know??
