Ooops... Forgot the other half of my reply...
Yes and the fish prolly wouldn't like the electricity flowing through the water either. Not to mention the toxic metal ions like tin and copper. LOL
Feel free to correct me if I am wrong, but I seem to remember the following from high school chemistry... Water in pure distilled non-ionic form is a perfect insulator, because there are no available atomic structures to carry the current. But as soon as you dissolve an ionic substance in the water, it begins to conduct electricity.
For instance, plain salt - NaCl, becomes a sodium ion and a chlorine ion - Na+ and Cl-. The examples are endless. My knowledge gets cloudy here, but I would suspect that the free electron on the chlorine atom is the key to the conductivity.
Metals and other conductors with metallic properties (ie- exotic ceramics) have a physical property known as "the sea of electrons". It's the movement of this sea of electrons that we know as "electricity", and is the conveyor by which it flows. Since electricity is the free flow of electrons through a conductor, I would suspect the free electrons on the chlorines ion begin acting like a sea of electrons and thus make a conductor.
