If you have "proof" relating to why people should use a ground probe in there aquarium I'm sure many people would appreciate you posting it here. I still don't see how all these codes you're referring to relate to aquariums.
I'm sorry if you feel I'm trying to "debate" this topic but when I give an opinion relating to such a serious topic I just feel it's a good to give reasoning. Call it what you want but how can you expect people to take you seriously if you can't give them explanation?
