Who has a grounding probe in their tank?

[Leah]

I have a question, I have 2 grounding probes and when the electrician was here doing
some work, I asked him about the testing, that is mentioned in the instructions. He had
no idea what it was talking about. So they are still sitting in the closet. Iam also a bit
confused as how they could zap the fish. Do they absorb stray voltage, Iam confused.
Please explain for us dumbies.

They complete the circuit- so if there is stray voltage, it flows through your tank. You stay safe, because you can't ground the tank yourself anymore, but the current still flows through the water. It's not as dangerous to fish as it is to humans, but it causes their navigation systems to go berserk. Messes around with the sensory pits in the lateral line, if I recollect correctly.
With a GFI, on the other hand, as soon as leaking electricity is detected, it shuts down the circuit. No damage. Of course, then you have to start testing to figure out which piece of equipment is leaking... which could be a PITA. But still better than taking a risk, IMO.

Before u buy one buy a voltage stick put just the tip in your water or on the glass even and see if it lights up if it does you need one if it dosent you dont have a ground problem

Easy as pie to hook up. One end is just a plastic probe, like a temp probe, and then plug the other end into an electrical outlet.

Does it matter whether it's direct into the wall or into a controller's power bar?

ah you're not a true reef aquariust until you've been electrocuted by your own tank. Sigh* ah the memories.

I would imagine the controller would be just fine, as long as you set that specific outllet to "always on"
