Good to know it was from the nem slowswim . Those things are really really aggressive and I'm not surprised at all you get a tingly feeling when you touch them.
That's more the case I was referring to as opposed to the ability of flourescents to impart very small amounts of current. Because of that possible scenario, you'll never catch me using a grounding probe in my tank. I'd rather get shocked sticking my hand in the water than having my livestock all die due to a dead short from a pump or heater failure. Been shocked before in more places than I can count
This is not to say that when equipment fails (insulation on power cords, for example) that fatal currents cannot be impressed in SW tanks.
