How many Hz do I need??

Hello I’m hoping someone out there can explain this for me. I’m trying to kill ecoli in the bladder. Dr. Clark’s says E. coli needs 365 kHz to be zapped. I bought a terminator 2 zapper that is 15 hz. I believe the terminator 2 does not have a high enough frequency. Can anyone confirm this? I think I need a zapper that will go up to 1 MHz correct? Can anyone recommend a zapper? Thanks all! Tweet
