    Pulled out my dev chemicals to find that the bottle of D-76 has some kind of residue, presumably Silver (Ag). If not, what is it? Will it be a problem when developing?

    Colloidal silver, D76 has a solvecy effect because of it's high Sulphite level it tends to dropp olut of solution.

    Every so often decant or filter the D76, and don't shale before use :D
