Just got zapped hard!

[scherzo]

I've often wondered why Neptune hasn't made some kind of voltage detector for the Apex. Or any other controller manufacturer...

Hmm.. maybe I should make something.

It really is as simple as having a voltage meter in the water and then the other end to ground. It could monitor the voltage in your tank.

FWIW you'll always get some stray voltage in the water. It is when it gets high that it is a problem. And yes - I know.. it is the current that kills you not the voltage... Either way - some way to indicate that it is safe for me to put my hand in the water.

Glad you survived. The most I ever got was an uncomfortable tingling. Found the heater that was the culprit.
