Davis, no, that water won't make any difference, go for it. And Davis, just some friendly advice. :)
Don't overthink it, keep it simple. An electro set up does one of two things, it works, OR, it don't work. Its that simple. As you go along, you'll find little ways to make it work better. Some more advice, get what SS you can, use it, it will work. If it don't work so good, get better SS the next time. It will all work, its just that some works longer, not better, than other grades of SS. Good luck to you.
