Just got zapped hard!

Get a cheap multi meter, stick the black end into the earth pole on a three prong plug, put the other end in the tank. Get a helper to unplug things one at a time, when the voltage drops to zero the last item unplugged is the culprit. Good luck.

Edit:
When a heater went bad in my display I had the same shocking experience, I didn't notice any damage to the livestock in the tank. The fish were a bit skittish, but no harm done. The fish that were in there are still in there after about 2 years.

holy frak! Glad to hear you're ok! Would hate for you to have yet another excuse not to finish your build.

All kidding aside, keeps us updated on what you find! You've got me scared to put my hand in my tank now!

remember that fish in the tank are not grounded.....

when you reach in, you probably are grounded and the current travels through you.... & thats what hurts.....

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.

I have a multi-meter. Would that work if I dipped the ends in the water?

LOL!!!! No excuse...YET. I'm still kickin! haha.

After work today I'm going to take the heaters out, and inspect all the powerheads as well. See if I can find anything obvious.

I would not recommend a grounding probe. A grounding probe might seem like a good idea to draw out voltage from the aquarium but it tends to draw more voltage into the aquarium that can lead HLLE and doesn't solve the issue of stray voltage in the aquarium. It is best to find out which piece of equipment is leaking voltage and replace. Just my 2 cents

I use one of these NOMA GFCI powerbars. It says not for use with aquariums but I use it anyways.

Wow - that is a hazard of the hobby I had never considered! I am glad you are okay. I stick my hands in my water all the time without a second thought. while doing a water change on the weekend, I accidentally dumped a bunch of water on my power bar and it started hissing and spurting. If the toxins don't get us the electricity will!

LOL, yeah thats the last thing I was expecting when I dumped my hand in the water!! Now im totally scared to do that again without using a multi-meter first! haha
