Shocked sensation hand in tank

Huskymaniac · Jul 18, 2019

I run three tanks and when I put my hand in my 750 I get a bad burning sensation in a small cut until my hand is fully submerged then it's all good. I tested this out in my other tanks and this is the only tank it happens in so I think I have a stray voltage issue. All of my ojmps are DC controlled except the heaters which are off on my Apex. Any ideas on what I'm should do or how to test?

Do you have a voltmeter? If not the easiest thing to do would be to unplug and stick your hand in until you find the culprit. Im guessing the burning sensation isnt the normal feeling of putting a cut in saltwater?

Check your AC pumps, I had the same issue happening in my tank, you can unplug the equipment one by one to see what is at fault .

I don't think it is. I tested my hand out in 2 other tanks and I only get the stinging in this one.

The poll only ac pump I have is my calcium reactor. Not sure if that can cause it even though it's not specifically in the water like powerheads, etc.

Did you ever figure this out?

I didn't. Input a grounding probe on the tank and it went away. I used a volt.meter and there wasn't really any stray voltage.

If you used a grounding probe and it went away, then there was stray voltage in the tank. Make sure you were using the multimeter correctly and try again... minus the grounding probe. I can only imagine it's going to get worse and effect the fish/corals. The grounding probe is now only acting as a band aid.

I ended up with a bad powerhead twice that was causing it for me, but Hester's are the #1 culprit.
