Just got my grounding probe, info needed on connecting

Iv heard loads of good and bad things about it, please let me know. Here are the pics:

 

FOR GFCI:

once, the lights im using has 3 pin. once i had attached just two pin by mistake and i got a shock. once i removed it, i saw that i had just attached 2 pin and the 3rd earthing (grounding) pin was not attached. once i attached that, i dint get the shock.
Here is my house main circuit. if there is anything bad hapning, it shuts off automatically.... i dont know whther its gfci or no....

 

All breakers are gfci. I dont know much about groundung probes as they pertain to aquariums though.

 

All breakers are not GFCI! The ones that are will actually have a GFCI reset on the breaker itself. The ones he posted are not GFCI.

 

if you see that "T" is a button, if pressed, will turn off everything....... what should GFCI look like?? and did u guys read above the photos?

 

anyone?

 

What you have is a "Earth Leak Circuit Breaker". This only looks for current in the ground line. A GFCI will also have a test/reset button on the breaker, but will say GFCI. These look for differences in current in the hot and neutral lines as well.
