Electric Shock Options

[Inxs]

Just now I found that there is slight electical shock when I come to contact with the water in the tank. Later, found out that the heater is mul-function. After removed the heater the electical shock is gone. Surprise to know that the goldfish can take it.

I heard  differnt.  But, I could be wrong.  I thought it still hurts them.  Low doses of current won't for a short period of time. 

Then there is the factor of salt too.  From the same idea of dropping electrical appliences into a bath or pool.  If we could be absolutly certain that there was no salt in the water or your body you would be fine.  But that is highly unlikely because you have salt and oils on your body. 

Please correct me if i am wrong though. 

Electrocution happens when there a return path for leakage current, the reason why the fishes have not problem is because before that all the leakage current are considered floating and will not do any damage (not return path to the ground.)

Unless the fishes touch anything conductive, in this case, like the hands of our bro Danny lor, then the leakage current will found a return path to the ground thru the fish via the hand and body of bro Danny.

And my advise to anybody adjusting any submerged equipement to put on an insulation media like rubber slipper or stand on a plastic stool. Just do a simple experiment, when you encounter the scenario described by Danny, just put on a pair of slipper, the stingy sensation on your hand will disappear immediately.
