Voltage is nearly irrelevant. A higher voltage will allow more current to flow in a less conductive solution which gets you to an ideal amperage over the surface area of the electrodes faster. If the current isn't limited to that ideal, excessive voltage allows "runaway" to happen. If the voltage is high enough and the power supply big enough to not just melt or catch fire, the water will boil away.
As the electrodes 'wear' they also get pitted and rough. That rough surface increases the surface area as the electrodes get thinner. Current discharge concentrates in points, corners and edges. ["lightening rods" are pointy for a reason] Rectangular electrodes will erode into spears, straight wire electrodes, into needles...both getting shorter and shorter...reducing surface area. Too much current on too little electrode will super saturate the water at and near the electrodes surface forcing the ions to find something to make molecules with ["particles"] For the most part, that will be oxygen produced by the electrolysis of the water making silver oxide *in the water* ["Golden Mist"] turning the batch yellow to brown..even black. Using a lower current , that oxide stays on the electrode where reversing the polarity can turn it back into silver ions, or it can be wiped off. Bending the tips away from each other to increase distance at these discharge points helps to prevent that. Flat electrodes have significant back side which doesn't contribute much to available surface area. Round wire electrodes have little backside effect and if the ends aren't in the water, tip discharge is eliminated.
