Yepper. I had the outlet that feeds my setup changed over to a GFCI before I set my tank in front of it.
If it ever goes bad I'm not sure what I'm going to do since it's trapped behind the tank now, but I'm glad I have it since it saved me at least once so far.
The GFCI was spuratically tripping out of the blue, and come to find out the housing of my return pump was all cracked up with parts of it getting wet that probably shouldn't have been.
