I have read all of that, and maybe my pea brain is on overload. Our supply water is very soft, it only has 10 to 20 ppm calcium to begin with. It is a SWG that we are going to use. I was afraid that if we dumped all that salt in the pool, it might be one big slimey mess with the water being so soft. We are currently using 3" chlorine tablets untill we get TA down and can hold PH to a decent level. Thanks for the input.
