What you are experiencing is known as galvanic action. Whenever
dissimilar metals are in the presence of an electrolyte, a difference
in electrical potential develops. One metal becomes the cathode and
receives a positive charge. The other metal becomes the anode and
receives a negative charge. When these metals are in contact, an
electrical current will flow, as in the case of any short-circuited
electric cell. This electrolytic action causes an attack of the
anodic metal, leaving the cathodic metal unharmed. The extent of the
attack is proportional to the strength of the electrolytic current,
which in turn is proportional to the electric potential difference
developed. The magnitude of the potential difference generated
between two dissimilar metals can be seen by the position of these
metals in the electrolytic series. When two metals are in contact in
an electrolyte, the one higher up in this series is the anode, the
corroded metal, while the one lower is the cathode, the protected
metal. The further apart the metals are in this series, the greater
the electrolytic potential difference, and the greater the attack to
the anodic metal. Note that silver and copper are quite far apart in
the series, silver being cathodic and copper anodic. Hence, when
copper and silver are in contact in an electrolyte, the copper can be
expected to be severely attacked. This causes the copper to be
attracted to the silver. This attraction of opposite polarities
causes the silver to be pulled out of suspension and deposit on the
copper. I would bet that steel, aluminum, and zinc which are even
less noble than copper would also do the same thing.

Initially, I used insulated copper wire wound around a plastic
funnel to keep it from floating when trying out the thermal chimney
stirring idea. [which worked quite well ]
I noticed that the exposed ends had collected a pretty thick black
fuzz on them. "What" ?
Batch of EIS @ 20 uS
Drop in 1 inch length of bare shiny copper wire.
In a few days, TE has vanished and wire looks a bit black.
Several day later, meter reading goes way low and wire looks
fuzzy/bubbly black.
Remove wire and rub, still shiny.
Look at reside. A mixture of silvery smear and black oxides.
Check water, nothing much there but water.
Copper apparently acts as a catalyst in ionic/colloidal silver water.
I've not noticed that any other metal does that, but then, I
haven't looked into it very far.
I do know that a nickel plated magnet has no such effect at all,
even after several months.
I found glass funnels that don't float. End of story.
Using copper for the [+] cathode seems to enhance Silver
Hydroxide formation pretty dramatically till it becomes silver plated..
I was playing with an *inertial acceleration from gravity vs
Cathode attraction to Ions * stirring idea, [electrical stirring]
not considering the difference between Ions and particles, but
observing directional effects of particles being moved laterally BY
ions in motion, using concentric ring electrodes of different
diameters at different elevations, using copper for the
larger/lower ring Cathode.
It DID interrupt that pesky "ion track" arc that was leaving hard to
remove deposits on the bottom, but didn't stir as well as thermal
convection currents for whole container uniformity.

Dear Ode:
Would you please elaborate! What do you think is going on?
Is it copper or any metallic substance?
How about a silver wire?

Drop a piece of copper wire into a batch of EIS / CS , wait a week or so
and observe using eyeballs and a meter.
..no more silver in the water.
