You are always better having one

Though some that is true, I fail to see how the ground probe in your house relates to ones in question. All house grounds are connected directly to appliances, they are not located on one side of the house, isolated so when a short occurs it has to travel through the air towards the isolated pole. All your aquariums electrical components are already grounded like every house hold item. You'll have to go more into detail than I'm an engineer and that's how it is.
