The tap water in Meridian definitely hasn't been softened. Matter of fact, if you run water into your sink it will bounce twice before it goes down the drain. ;) I used to measure out my SWS, so much to each 5 gal of water I added, not anymore, I haven't added any in quite some time and it still works fine. I like to use around 20A, but with my Schumacher Charger I have to set it at it's lowest setting (6V Low) and it starts off just fine, right at 20A, but as the piece gets cleaner it will increase the output and get up there around 40A. I don't know the thickness of my SS, all I remember is that it sure was a B&@%$ moulding it to the shape of the inside of the barrel. I finally ended up, rolling it up, tying it up with some twine, placing it in the barrel and then cutting the twine. I hope it works out this time for you Chuck.
