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. http://ca.mouser.com/Semiconductors/Discrete-Semiconductors/Diodes-Rectifiers/Current-Regulator-Diodes/_/N-ax1ml?P=1yzrlz3Z1z0rzzo
Do I need to get at least 5 Volts?

Im sure it was  1ma per square INCH
I actually use 0.2/0.1 ma per square inch for much better and easier results.... It takes longer but its worth it... High likelihood of having Higher Ionic content.
