A black surface soaking up the suns rays will heat that area in the water more than all the other areas. Warm rises, relatively cooler sinks [Temperature differential ] and the water circulates. ["Thermal Stirring"]

Stirring does reduce deposits, especially where an un-interrupted ion track might intersect the container, but may not eliminate them as the majority of crud [but not all of it ] comes from water contamination being "used up" by highly reactive ions forming nonconductive particulates...in effect, further purifying the water as that insoluble crud falls out, as added ions that don't find a reaction partner make it more conductive with soluble ionic *silver*.

So
The crud is a "good thing"...to leave on the bottom...as the top becomes more refined by its dropping out. The *generator* always does the same very simple thing in a massively variable and extremely reactive environment.

A low frequency alternating current output to the electrodes eliminates DC ion tracking thus reducing the need to stir and those direction shifting traveling ions have mass and velocity, thus will move the water some, molecule by molecule by impact, but mostly only directly between the electrodes.

If the container is mostly filled with electrode, that's generally enough stirring.

Ode, could you please elaborate on the strip of black tape or paint? Would that keep from crud from accumulating on the bottom?

So long as you use pure silver and pure water, there are no photo-reactive compounds made and you can run batches in direct sunlight...and... use a strip of black tape or some paint
 to make the sun stir it.
