I have read a few of the messages here and I am curious with a 27000 gallon pool how much salt would I need to throw in to make a difference. And I knew before I posted this it would probably get blasted, by read other post comments, but I wanna get the advice on my thread from the smart peeps here. So 80 lbs what kind of an impact would I get and would others be able to notice. And is it worth it to do so?
