i constructed a clark zapper. after lots of reading, i've noticed there is a lot of confusion about which frequencies to zap at. some people say 30kHz does not work well at all, and others say 30kHz works best for killing parasites, and so on.
I made it adjustable and can set it from 500Hz to about 50kHz, i was thinking i'd lock it in on 2.5kHz... can someone please give me some direction? I had it at 1000hz and then noticed that frequency is only used for the food zappicator which isn't what i want. i want to kill critters and parasites with a zapper. hell lets kill everything. or at least lots of things. please help me kill them until they're dead.
