Interesting. At work, we make deminerized water. We keep the pH at 7, conductivity less then .005, and silica less the .005. All the other crap, we keep it less then .001. Got 250,000 gals tank full of it.
For waterwetter. I know people running distilled/deionized water. Use to be able to get it from wallymart. Also check out EngineIce.
