Stray Voltage...

[hbtl_ofndr]

... so every piece of submersible equipment that I have ever tested emits a small amount of stray voltage. At what point does it become a problem and start negatively effecting livestock?

Also, what are your thoughts on grounding probes? Personally (and from a purely electrical standpoint) it seems like a bad idea to me, as voltage really isn't an issue, current is. And by introducing a grounding probe you are introducing full time current.


Thoughts?

Stray voltage is thought to be a major contributing factor to Head and Lateral Line Erosion in Acanthurids. I've always been of the school of thought that a grounding probe is a great idea. So yeah it can harm livestock. I'm not an electrician so I'll leave it at that.

What's the reading on the volt meter and we can go from there.

Sounds like a Chad question !!

Return pump: 1.8v
Skimmer: .9v
Evos: .9v
Heater: 2v

Total: ~6.3v

Just put a titanium probe from MD and u will fix it.

What exactly will it "fix"? voltage from submersibles will still be there, but now there is 24/7 current. From my understanding only thing a probe protects is YOU from getting shocked because YOU are the ground if it's not there.

Let me rephrase the question: At what voltage/amperage does electricity become detrimental to marine life?

Im no electrician, but since fish are in the water they wont get shocked, because they are not grounded(think birds on a telephone wire), right?. Wouldn't the water around them always be the path of least resistance to them? Thats just my 2 cents, and i cant account for benthic creatures and corals.

Hope this helps

Hmmmm. I'm always using my phone so my search feature is as useful as Sanh at giving directions in English.

I made a thread on stray electricity 1.5 years ago in here maybe less. Are you testing from a known ground on the black side and then red into the tank water?

I found my stray juice by the old turn one off and measure, till I found the current. I believe mine was leaking 18v total. Old Koralia FTL.

Oh an that's why your fish have gone to eating the coral while its hot. Haaaaaaaaaaaa!
