I have no idea. Part of the reason for using high voltage at high frequencies it so that the particles are sufficient far from the anode they all do not get pulled back on the next half cycle. At 10 Khtz, the period is so short, I am surprised you get much production at all. Perhaps convective currents are assisting by adding stiring. I am curious. How long does it take to produce how much CS using what current? My setup produces 200 ppm gallon per amp per hour (4 gallon per hour of 5 ppm at 100 mA).
