Serious dangers of salt water tanks and any tank

[1eyedjyde]

The current in the tank comes from a faulty device such as a shorted powerhead it grounds on itself until the stupid human stick his hand in the tank to grab the powerhead without unplugging it first.

Ok where to start...... If the power head was truely shorted, the current would have exceeded the rating of the over current device, usually being the circuit breaker, therefore the breaker would trip and there could be no current.
Current can not flow or exist unless it has a path to flow on, therefore current cannot be waiting in the tank. Current is the result of voltage on electric circuit.

Please refrain from giving advise to others on a public forum on topics that you have limited understanding and knowledge on.

That clearly wouldnt happen, the fish arent grounded. Its like birds landing on power wires, no death, but if they where to contact 2 wires at the same time....poof, cooked bird.

GFIs and power bars are good investments however a GFI will only help if it detects current coming from one item so plugging a GFI into a power bar does you no good you have to use a GFI for each piece of equipment you plug in however that being said I have seen GFI power bars but know little about them aside from that they are flipping expensive

Sorry man this is simply not true, one Ground Fault Circuit Interrupter (GFCI) can detect faults in several things. You do not require a GFCI for each device.

So if I have my powerbars plugged into a CGFI outlet, each device plugged into the powerbar is protected? I often wondered that. A lot of us use controllers with powerbars. If the powerbar wasn't protected by the GFCI then the GFCI would be useless. So I understand this is not the case. Thanks for the clarification.

A powerbar plugged into a GFI will protect all the devices down stream.....so yes.

If the powerbar wasn't protected by the GFCI then the GFCI would be useless. So I understand this is not the case.

Not sure what you mean here..

Thank you very much, its nice to hear that it is appreciated!

I believe molotov is talking about an incorrect statement in an earlier post that you need a GFCI for each device.

[Dearth]

That was me with the incorrect statement about GFIs and thank you for correcting me on it because when I got into aquariums 18 yrs ago the GFIs I had would do nothing with power bars and ended up buying 9 GFIs for the 3 tanks I ran.

How things change over the years

Voltage and current can leak threw the tank without you putting ur hand in as for fish well think of a bird on a line my hand was fully submerged and nothing until I put my hand on the tank witch then created a circuit as treated me as ground

[isaac1]

Oops my bad didn't read that last one you put there mr out of controll
