You will find a flow through process much more reliable, faster, and more consistant. Plus you can easily change the ppm easily by varying the flow rate when using constanct current. Using non reversing current, you will end up with a significant amount of the silver plating out on the cathode, and eventually breaking loose and falling to the bottom. I would reccomend using a smaller container, about 1 gallon, flow through processing and a reversing constant current source. That is what I use to produce 55 gallons at a time, at the rate of about 1..5 gallon per hour per 10 ppm.
