Re: phosphate



You guys might want to look up the compound
"Sodium hexametaphosphate" or "sodium phosphate glass" sold under
the brand name of CALGON (Kodak) its used to soften the water
without precipitate formation. I used this in my photo darkroom.

When I used it in my darkroom I did get precipitates.
