Stray current, stray voltage??

[skyjuice123]

Here is a forum page with video that talks about voltages in aquarium

A voltage of 10 volts should be considered as induced voltage and not voltage leakages if you use a multimeter with one end of test probe on electrical earth lead and the other test probe in the water.

Salt water is an electrolyte. It is said to have enough power to light up a small light bulb in this experiment depending on the amount of salt.

As for the occupants in the tank, it is the voltage gradient or volts per meter across the water that will be more harmful than the voltages between the tank and the electrical earth. This voltage gradient would generate current that might cause dead fish or unusual behaviors in the fish

Because water is a good electricity conductor, the voltage gradient should be in micro or nano volts. This is not measurable by normal multimeter. Wonder if any brother/sister here have carried out any experiment or come across work being done to detect or determine the deadly voltage gradient.
