It's connected to a surge protecting power strip. I'm guessing that the resistance of my arm was still high enough that the current wasn't seen as a ground fault. In this case a GFI may not have helped anyway.

I tested all the outlets afterwards. I originally thought the light was shorted as it was new and that something was wrong with the ground line. After the light case, and the outlets checked out ok, I realized that there was something shorting to the water, and I just grounded it to the light with my shoulder. Testing from water to ground with a voltage meter confirmed that something was fully shorted into the water. Never would have thought the plastic heater would be the problem.
