I'm not an electrician or a physicist, so take this thread with a heavy grain of salt. I guess I've always assumed it doesn't much matter where you put the grounding probe -- if there's current in your tank, it will find it. Maybe that's not right. I thought that current looks for the easiest path to ground. So long as the point where the current enters the water and point where the probe is wet, there will be dissolved materials in the water between the points sufficient to make the current go in that direction.
I suppose there may be circumstances in which current flows in a substantially direct path between two points in an adquarium without diveriting. Tough to imagine, given all the flow and and potential for movement in the aquarium. I suppose if that's the case the soundest place to put the probe is close to where you'd put your hand in the water, since it seems (to my very uneducated mind) that it's unlikely the current would use you to go to ground if it didn't use the probe.
