HELP, Flexwatt shocking cage NEED HELP

[JWFugle]

so i have an AP cage setup with flex watt and i get shocked if i touch the substrate without shoes on.

i have triple checked my connections, rubber sealed( sticky rubber tape that comes with reptile basics flexwatt conectors) all conections. im at a loss and way to irritated over something so simple causing so much trouble. i noticed before the animal was in there so thanks for that.

i tried running a ground from inside the cage with aluminum tape and running that to a wire which i then plugged directly into my surge protectors ground plug. didnt help, still got shocked.

i have mulch and topsoil in the cage and only the top soil shocks me. so some how i believe it is inducing a charge on the topsoil. but i cant figure out why it wont go away when i ground it.

please help, ive read several other forum pages who had similar issues and none ever figured it out
