Don't over saturate the water in high concentration zones...such as..at
the electrode surface in the Nernst Diffusion layer...a micro zone.
ie Keep the current density down [millimaps per square inch of electrode]
Keep the water moving so as to not set up macro high concentration zones
Since the human eye can detect a single photon, but doesn't have the
resolution to distinguish between photon streams below a threshold
diameter, a laser beam can give you a pretty good idea of particle
size...it's just not calibrated like a Malvern particle sizer.
If it looks like velvet...the eye is at its limit.
The limits are documented, but I can't figure out how to make a language
translation from ocular angle speak that includes distance, into a diameter
seen from a given distance.
Simple question, very complicated answers.....
How small is too small to tell one from another when it's right in front
of you, being magnified by the optics of curved water filled glass?

less to do with the particle concentration than the particle size. 1/4
the particles of twice the size will show up as 4 times as bright.
What is the best way to make the smallest particles?
