Koralia Killing My Fish?

Is it possible for a Koralia 1 to release enough stray voltage to cause my fish to have serious problems over night?

I added a Koralia 1 last night and then this afternoon my six-line is MIA and my Yellow-Tail Damsel is having serious problems (rapid breathing, not swimming around).

Has anyone heard of this happening?

I also posted this on my tank thread:

its is possible for any powerhead to throw enough voltage to kill fish in you tank i would suggest taking out koralia. and geting a grounding probe either way. was it a new koralia? im not sure how to test if it is the koralia or not

how are your parms

 

A grounding probe is an essential piece of equipment. I would take out the korolia and look it over and see if the fish get better.

 

Yes, it was a brand new Koralia that I just got from AquaCave. I have unplugged it for now. I do not have a grounding probe, so I will look into getting one of those and then try the Koralia again.

Will a grounding probe effectively counteract any stray voltage?

Params are in my sig.

 

There seems to be some disagreement about these grounding probes. This site seems to suggest that grounding probes will do more harm than good:

Aquarium Grounding Probes

Either way, I'll just have to see if the fish get better with the Koralia unplugged.

interesting article, it does make sense. but i wonder if it is really true. i was about to set a grounding probe in my tank as a precaution.

anyone currently running a grounding probe found that they have had more problems are install. but the article did have a point grounding probe is only a band-aid, you need to deal with the real cause, in your case the koralia

 

The article was actually false IMO. Stray voltage comes from a lot of things. The electronic lights that we light our reef tanks with. The light penetrating the water in itself can cause stray voltage. No way to solve that is there? Heaters are another. Heaters operate on an electrical short. Stray voltage can jump the coils, through the case of the heater, and enter the tank, under normal operation. Grant it both of the things I just listed are small, but all that small stuff can add up; specially over time. A grounding probe is a integral part of equipment.

On another note, without a multimeter and doing tests, there is no way for you to even know if its voltage thats causing the problem. Adding more flow can and does stress fish. I would think that would be a much more likely cause than the very slim chance a brand new koralia is leaking voltage.

 

i never said he was right, that the first i have heard that a grounding probe was bad. some of it makes sense. i just want to know if anyone has ever had this problem? i have never used one so i am not an expert. do you use a grounding probe?

 

i do not use a grounding probe, if you have your tanks pluged into a GFCI you will not get any stray voltage in your tank,

 

Well, here is my assertion, I think a grounding probe is a viable preventative measure. It is in our tank in the event that there is a substantial amount of current present and the probe draws the current out. This is taken from the article; "My belief is that if there are any stray currents in the tank coming from an electrical appliance, the solution is not to try to draw the current away with a grounding probe (symptom), rather, the appliance must be damaged and should be replaced (cure)". Here, even he admits the current gets drawn away. How can he be saying the probe will act as a circuit producer and then say it draws the current away? O.k. enough said on that. Probes do exactly as they were designed to do, draw current away (out) of the tank and that is why I employ one.
