I am buying a inground pool kit. They are selling a mineral ionizers. I have in my above ground pool I have now a swg from intex and it was recommended all over here to not not hook up the small plug every one said it will put copper in my water. I have been reading about the basis on the mineral ionizers and said it put copper and silver in the water. Anyone using it how is it doing do you like it? Pro's and con's please
