I use melafix and salt with a tmp around 85 f* Sorry this combo didn't work. You could try separating power feed the silvers so they can get some size on them and try it again... Jars are mean and more powerful per inch then silvers, but silvers get much larger... If your silvers were say another 2 or 3 inches larger then they are you'd have a much better chance of this working IMO anyway.
