For the LAST time! (i hope anyway)
It's NOT, i repeat, NOT a magnetic field.

Ok. First a quick refresher of your highschool physics and chemistry.

1* Two different metals with different electronegativity ,according to the Pauling scale, in water corrodes faster when free ions are present in the water (thats why deionised water is good to prevent corrosion, in the beginning anyway).
2* A ion has a elecric charge (positive or negative).
3* Any item with a positive or negative electric charge will be accelerated in a electric field.

Now back to the idea.
How do I reduce the number of ions in the water and by that slow down the corrosive process.

Would a elctric field across/through a vinyl tube attract/repell the ions to stop at that point in the tube?

It would be fairly simple to calculate this if the ions came "flying" through an empty tube. However the water is also present and provides a flouidous resistance. So my problem is I don't really know how to take that into the equation.
