Someone mentioned a lot of sparklies when using a bubbler. This could be dust and pollen. A thought here... If one adds just a little H2O2 to the water at start, silver flakes will form. Is it possible that adding a lot of oxygen to the electrolyzing water [by bubbling] might make some hydrogen peroxide?
Stir speed: I've found that stirring too fast promotes a build up of a fuzzy grey deposit that grows opposite to the direction of the water currents. I believe this to be caused by water pressure keeping the size of the hydrogen bubbles so small that their bouyancy won't overcome their adhesion to the electrode and silver becomes deposited on the surface tension of the water/bubble interface. As the hydrogen bubble is stabilized in size by the coating, a new bubble forms and also becomes stabilized. Eventually, a structure forms on the electrode that falls off into the water as light grey chunks. Also, this build up is only semi conductive and slows the process [keeping the hydrogen bubbles forming slowly]...sometimes developing a feedback loop that just makes the structure bigger and deposits little silver into the water. The upside to a bubble system is that it might knock those hydrogen bubbles loose before the structure can grow. The downside is a possibilty that H2O2??? could form and the addition of so much oxygen might increase silver oxide levels. I have found that freshly ozonated water produces more oxide deposits than the same water that has been outgassed. I have found that a high speed DC motor will do a good job if the stirrer is straight. The rate of stir can be adjusted by shortening the stirrer. Just 3/8 of an inch of a spinning straight cylindrical stirrer exposed to the waters surface creates a vortex that reaches the bottom of the container like a slow tornado. Place a tiny piece of paper in the water to see just where the currents go. It spirals down the center of the vortex and wafts up the outside of the container when it reaches bottom. A longer stirrer can make the water look like it's going down a drain. The slower the currents , the better...as long as it keeps all the water moving.
