Tank contains Voltage

[kkgaskin90]

I can't figure it out either. The stray voltage was my last guess. I treated with Kanaplex, removed Carbon, feeding good food, soaking in vitamins... :( this is depressing.
And I know vitamins won't cure... But they were suggested and I'm willing to try anything that *might* help.

Those induced voltages you have in your tank are actually very low compared to most tanks. HLLE so far has no cure and no known cause. Voltage was one theory as was about 20 other things with carbon being the latest theory. What do you feed your fish and how old are they? "Good food" doesn't mean much to me. Do you use carbon? What other fish do you have? I really don't care about your water parameters as they don't cause disease in fish unless they are way off. It is usually food.

 

[kkgaskin90]

Interesting. No Carbon. Rod's food and LRS.. Also gets nori.

 

[kkgaskin90]

I've had it almost 2 years. Other fish are Flame Hawkfish (also 2 years), Kole Tang, Sleeper Goby, and Anthias.

 

[Paul B]

Those foods are good, do you have a picture of the fish?

 

[kkgaskin90]

Yes. Here's a few days ago. I'll try to get a new one since it's worse today.

Of course that hippo has classic HLLE. HLLE is not fatal as I have had hippo's with it for 10 years but it is certainly a disfiguring disease. I have my own theory as to what causes it but I don't want to get into that, besides there is still no cure. It is "caused" by captivity as wild tangs do not get it. I have stopped the progression on French Angels by feeding vitamin A or fish oil but that was many years ago and although the fish were cured, they never "completely" recovered their color. But they looked markedly better. I would get some live food into that fish such as live blackworms every day. Unfortunately soaking food in vitamins other than that will do little to cure that fish. That has been tried for decades. To get vitamin A into that fish, put some fish oil on dried nori and feed it to him. You can not put any vitamins, expecially oils on wet food as it will just rinse off as soon as it hits the water, but fish oil will soak into dry nori. Remember I didn't say this was a cure. But I have made fish much better by doing that every day

 

[kkgaskin90]

Worth a shot. Not sure why all of the sudden she's getting so drastically worse :( fish oil as in the regular stuff in capsules that you buy in the vitamin section?

 

[Paul B]

Yes, that's it, while you are at it, take them yourself, they are good for you. Let it soak in the nori for a while or you will make an oil slick. I feed this to my fish all the time along with live worms and some of them are in their 20s

Great thread!
Learned something new about stray voltage and currents.
Not to mention that my fish will go on a Nori/fish oil diet topped off with black worms (no racial intention here) ............. and for that matter me too........... this hobby can be stressful by moments.
Just to think if we didn't had Paul B in the group, where would we be??

 

[Paul B]

Probably in Bayone New Jersey

 

[Diesel]

For ppl who don't know Bayone............Bayonne is a city in Hudson County, New Jersey, United States. Located in the Gateway Region, Bayonne is situated on a peninsula located between Newark Bay to the west, the Kill Van Kull to the south, and New York Bay to the east.

OK, back to the power of Voltage.

I had to get a grounding probe as well and since then did not have any issues with my previous tank. I would still make sure that some of your equipment isn't putting off too much.

Induced voltage will not trip a GFI breaker when a grounding probe is placed in the tank. If it is actual current leakage it will trip the GFI. You have a GFI in a GFCI it is just another acronym for a ground fault breaker. The way it works is it compares the current draw from the hot side with that of the neutral. If it differs the you have leakage direcly to ground and it will trip. This is suppose to save lives. So if you place a grounding probe in the tank and you do have leakage in your tank that is not induced then there will be a difference in the current from hot to neutral. Hope this helps explain things a little.

A float switch can cause stray voltage on AC if the ground of the DC supply is not a neutral. That is likely that it is not. It is usually a floating ground.

So ground probe to GFCI=good?

 

[n2585722]

If you use a Ground probe and GFI and you do get real leakage it will trip the GFI and shut down you equipment on that breaker. That beats getting shocked in my opion though. I would not put a grounding probe in a tank without a working GFI breaker. My tanks is feed from 2 different GFI outlets. If one trips the other will keep running unless i have two leakage failures at the same time. That is very unlikely. At this time I don't have a grounding probe.

 

[kkgaskin90]

I think I understand. On that reasoning, I thought maybe plug the ground probe in to a GFCI outlet further down the line and the equipment in to a separate GFCI, but if they are in the same line if one trips, the other will too, correct?
Loss of power isn't a huge concern of mine since I stay home...

 

[n2585722]

The grounding probe does not have to be on a GFI outlet. The probe itself will not cause a GFI breaker to trip if the current to ground is from another line. The probe only uses the ground of whatever outlet it is plugged into. The GFI monitors neutral and hot.

 

[redfishbluefish]

The choices you have are to either have a GFCI or have a GFCI with grounding probe. The GFCI detects difference in current flowing "in" to that flowing "out." Any slight deviation and it will trip. Just like when you stick your hand in the tank, you don't have to be "plugged into the same circuit" for the GFCI to trip.

Now you can use a grounding probe without GFCI, but when you have a voltage leak, you'll energize the tank and potentially electrocute your fish.
