Has anyone found any differences in the quality of the DE offered from different companies? I see the Wolf Creek site says theirs is pure white and that some are yellow or tan (higher amount of iron) and some are grayish (higher clay content). None of the other sites I looked at mention anything about their color. So I am interested in if anyone has tried the DE from more than one source and can comment on this.
Also does anyone know of a local source on Long Island, NY?
