Now this I don't understand. If Mag pumps do this, how can you ever have them in a system with a grounding probe and a GFCI? It should trip immediately! Anyone know what the threshold for a typical GFCI is? If its not going to trip pretty easily, its not going to be much of a safety device either, I wouldn't think.

All (many/most??)mag pumps will put out small amounts of stray voltage - generally not something you can feel. However, if you have enough of them, they can be felt. On my 215 I have 2x1200gph closed loop pumps, an 1800 gph return pump, a 1200gph skimmer pump, a smallish pump on my Ca reactor, and 2 Seio 2600s. This was enough to add around 12v to my system - and enough to get a tingle. I thought I had a short somewhere, and with a multimeter, managed to find out that ALL of these pumps put out a volt or 2! A grounding probe - along with GFCIs - "fixed" the problem. I say "fixed", because the voltage is still there!
