I've never had problems storing it in transparent bottles. I pre-mix
all my dry goods, trace mixtures seem to be the ones that are more
delicate to light. My CSM+B got some fungus in a clear container for
example.

Hope that helps

If I mix up some Potash in solution do I need to keep in in a light proof
bottle? I know my Potassium Permangenate solution is supposed to be in an
opaque container. So I would imagine Potassium Chloride is the same?
