Just got zapped hard!

So the return pump is submerged? I'm in the "the fewer electrical cords in the water, the better" camp. I don't have a return pump on my sumpless set up, but once I upgrade to something with a sump, it will have an external pump. Haven't measured tank voltage in a long while, I have VorTechs as well, so no powerheads with cords in the tank. Heaters & skimmer feed powerhead are the only electrical components physically in the water & I make sure the cords on those items are above the surface.
