Ive received what seem to be small shocks when putting my fingers in my aquarium sometimes, really stings if I have a small papercut. I decided to check for voltage, and was "Shocked" 
to find a decent amount.
I connected my neg/black from my meter to my grounded copper water pipe, and submerged my pos/red cable in the aquarium. I got 47V AC. That seemed crazy to me, like it would fry all my fish, and me even, but may not be much amperage to back it up, which would make the shock less painfull.
I tried unplugging both my heaters first, and tested little to low voltage (0.002). I then plugged in 1 heater, tested 6vac. Then tried just the other one, 13vac. After that,tried plugging both back in, and got 16volts. Much less than 47v on first test, but still doesn't seems good.
Both heaters are those black Stealth shatter-proof 200w heaters by Marineland. Supposed to be able to fully submerge. They are about
3 yrs old, and heat just fine.
I feel I should do something, probably starting with throwing out those heaters, but wanted to see if you guys had ran into this prob before, or knew a way to prevent or eliminate it.
