I believe that should be 1 mA per square inch, not cm. There are about
6.5 square cm to a square inch.

I answered it earlier. 1.7 is great, 5 would be ok, but I would not go
over 5. After all, lower is better since that defines at what voltage
the diode actually starts working.

square centimeter of what? the surface of the electrode in contact with water?
I think that this is too much complicated. I have been using CS for almost 20
years now, and I would say that it is sufficient to use very pure water. When
you use your apparatus you
Yes; you're right!
Thanks for the correction.
Still, no one answered my question. Is a Maximum Limiting Voltage of 1.7
V good enough, or do I need to search for a diode that goes to 5 volts?
There are only 2 current limiting diodes at 1mA, and the Max. Limiting
Voltage is only 1.7 V.
sheet (free) to see how it works. A 75 ohm resistor will give you
about 1 mA.

Please consider
That is the maximum voltage drop that is necessary to go into current
limiting mode. Any lower drop across the diode and it will act more
like a resistor than a current source. At 30 volts, anything under
around 5 Volts should be fine for that.

Do I need to get at least 5 Volts?

With 30 V dc use a 30K resistor. V=IR where V=voltage I=current. To be accurate
you have to consider also the resistance of the water between the electrodes
which varies with the conductivity and the distance between the electrodes. May
I ask why you need to be so accurate?
I have been advised by many on this group to keep the current down to
1mA per square centimeter, in order to have nano particle size.
