Here are full-resolution (2900dpi) neg-scans of photos of a Stouffer wedge shot on TMY2. The left scan was developed in distilled water, and the right in a tap-water solution that was allowed to sit for one hour at 20C before usage. It had some cloudiness visible in specular side-lighting, which was the beginning of precipitation.

Yes these pictures are boring. But I don't see any degradation in the dark or light areas in the right scan. Nor do I see any issue in a 22X loupe on the light-table. The cloudiness appears to have had no effect. If waiting an hour doesn't hurt anything with hard tap-water, I'm questioning whether it's worth putting a chelating agent into this one-shot formula. I guess I should run more tests to see how severe the cloudiness must be before it affects image-quality.
