Who has a grounding probe in their tank?

Easy as pie to hook up. One end is just a plastic probe, like a temp probe, and then plug the other end into an electrical outlet.

Does it matter whether it's direct into the wall or into a controller's power bar?

ah you're not a true reef aquariust until you've been electrocuted by your own tank.

Sigh* ah the memories.

I would imagine the controller would be just fine, as long as you set that specific outllet to "always on"

I always run a ground probe and GFI.

If you find my thread where the arc went from my pendant to my forehead, when I had the probe out and was fine with it in, {current leaking from a stream pump}, you will see why, plus some good posts there from electric oriented aquarists.

Curious. Is/are your pendants grounded? I've measured close to 200 volts from my clip-on (ergo isolated) T5 reflectors to the water. Used to get tingles when touching both the reflector and the water. Attached a wire from each reflector to ground and the large induced voltage is no longer present. Although it is a high measured voltage, the current capability is obviously not that much or I would feel more than a tiny tingle. Could be that the arc to your forehead was also caused by a large static charge, walking across carpet in a dry room, then touching a metal object. Voltage needs to equalize, so big snap but generally not that harmful.
