ha, install one please, or maybe you might not be posting here anymore. ]]]bdwn on a side note I was sliding my canopy off the front a month back and I have a fan clipped on the back of the canopy to keep the mh cool, well I forgot to take the fan off before I start taking the canopy off. Well you can see where this is going. The fan fell into the water and the GFCI tripped. Now, no hands were in the tank at the time the fan fell in but if a hand was in there and I did not have a GFCI, I probably would not be posting here right now. So do yourself a big favor and install a GFCI. They are life savers, no seriously they are!
