Rid-Volt Grounding Pole
Very worthwile if you are using pumps or electricty around your tank. [img]images/smiles/icon_eek.gif[/img]
In the event any of your electrical components ever short out, this will prevent it from killing everything in your tank. I may also save you from electrical shock as well.
Every tank I have has at least one of these items. You can usually get them for about 12.00 USD and considering what they may save it is money well spent.
