No! Just because a power strip has a reset button (circuit breaker) doesn't mean it's a GFI. It must clearly be labeled as one. Also it will have a test and reset button. GFI's work by sensing faults to ground. If a device fails and goes to ground it will rapdily discharge current to ground. GFI's are actually an extremely fast circuit breaker that sense the "lack of voltage potential" from the hot leg to the nuetral leg OR ground wire. They have been around since the 1980's and have been written into building codes in most areas.
GFIC does NOT mean grounding for indirect current. It means GROUND FAULT INTERRUPT CIRCUIT.
Further, any device operated from AC
(alternating current) produces rising and falling magnetic flux lines perpendicular and parallel to the ac
sine wave of electrons flowing through the wire. In the US we use 60 cycle power which means there are 60 perpendicular and 60 parallel energy fluctuations per second. The magnetic fluctuations CAN induce current flow in electrically conductive objects nearby. However tiny, the induced energy can be measured. For example, if you were to lay a lamp cord (with lamp turned on) across a piece of metal you could actually measure a miniscule amount of electricity in the metal that is induced from the rising and falling magnetic fields. Normally it's so small we consider it to be insignifigant and harmless. However, in saltwater things change because saltwater is HIGHLY conductive. Any submerged motor, heater light, etc, produces eddy currents in the water which won't kill fish immediately but can have term deletrious effects on their central nervous system. A titanium ground probe is the only way to safely discharge these currents from your tank to an earth ground.
