how does AC electrolysis work .. need help

[crytalline silver]

specifically im using AC 10,000 volt process in distilled water one lead in solution with crystalline silver , silver crystals and other about 6 inches apart and 1/4 jnch above solution producing a constant purple arc try n to make silver colloids small nanoparticles 0.2 to 0.3 nm range ... my TDS reads 0.00 ppm at start and 3 hrs later 300.00 ppm and solution is crytal clear ,now when i used DC low voltage process the solution would turn light grey or yellowish between 10 ppm and 25 ppm my conclusion that if i can see something in solution then must not be nanoparticles in smaller range of between 0.2 & 0.3 nm any and all advice or assistance will be helpful thank you for taking the time to look this over ...ive heard tale there are no stupid questions only stupid answers but im sure i can change that !also heard crystalline silver may have a peizo electric property how may this effect the outcome of of reaction also ive heard that nitrogen can be infused through the arc any thoughts on how to stop or lower the amount of nitrogen entering reaction ?thinking vacuum
