Oh I understand how it works... But what is the point of the shock once a week? My question is this... If you shock once a week when the water temp is over 70* using liquid chlorine, and that brought the chlorine level up to lets say 15ppm, then what is the purpose of the product? If your levels are up that high (shock level) then what good does it do? From what I read, it would be like saying this. I am going to sell you a gallon of bleach. Do not take the lid off, just place it in the water and let it float around. If the water temp exceeds 70* then take another gallon of bleach and poor it in and bring it up to shock level once a week. :? Maybe I am just missing the concept. I am sorry if I offended anyone.
