To be fair,the original "recipe" for the ice cube method includes powdered water softener and warm water to loosen up any hard deposits and paper in the tank.Let this mixture stand overnight then add about 20 lbs. of ice before you leave for the campground.Upon arrival,head to the dump site before you set up.
