Either voltage will work just fine on that size tank but 2 amps is a bit low. 8-12 amps @ 12 volts will work. 24 volts might speed it up but it might also heat it up. Remember that you'll be generating hydrogen gas so you might want to set it up outdoors.

Old lawnmower blades work very well for the sacrificial pieces. Just be sure to get your polarity correct - "positive attracts" the rust from your project piece. This is the key to remembering how to hook up your charger in order to not "sacrifice" your project part.

It is not a perfect solution but it is inexpensive and very helpful. Patience is required.

1. Before.
2. A few hours in (another reason to do it outdoors - expect a mess )
3. 24-48 hours later, I forget exactly. I think I had also lightly wire brushed it, manually.

"Passionate hatred can give meaning and purpose to an empty life. Thus people haunted by the purposelessness of their lives try to find a new content not only by dedicating themselves to a holy cause but also by nursing a fanatical grievance. A mass movement offers them unlimited opportunities for both."
