Stray voltage in my tank

Last week my regal tang began acting very nervous and was swimming into the walls and doing a lot of hiding. It looked as though maybe there were some bumps on her lateral line. So after doing some reading about HLLE i decided to test the water for stray voltage. My husband has a volt meter so when he got home we tested it and there were 48 volts of electricity in the tank.:scared: We put a copper wire in the tank as a ground and the voltage went down to 0. After a couple of hours I thought OH NO copper in my tank and took it out immediately. Next day I bought a titanium ground wire. With the ground wires in my tang was so much calmer almost immediately.
I checked my heater and it attributes for about 9 v., the powerheads 9 v., and lighting maybe 1 v. So where is all the remaining voltage coming from? Does it build on itself or is there some type of multiplying of voltage going on? I can't explain it can anyone?
Also my advice to anyone is to put a grounding wire in from the get go. The one I bought was only $17. Well worth it for the health and happiness of the fish as well as the safety of yourself sticking your hand in a tank with stray voltage.
The end of Oct. I began losing fish (8 out of 11) over a couple of weeks. Ich, bacterial infection?? Now wondering if the stray voltage did not have something to do with them being stressed and getting sick.

Good post, ocikitty, and real testiment to the need to use grounding probes. Especially in tank with tangs.
