I'm very intrigued by FX-55 and have mixed up a batch of the "A" solution. I'm wondering if there's any detriment to pre-measuring the "B" chemicals and storing them combined in individual sealed plastic bags until use. That way I can pre-measure everything and then at development time simply: -> Dilute Solution A 1+9 -> Pop open a pre-measured package of the "B" powders and mix them into the dilute "A" solution. -> Pour into the tank and start developing. So I guess I'm asking if there's any problems storing the pre-measured: 1.3g of Sodium Ascorbate 0.1g of Phenidone in sealed plastic packages. Will these two chemicals interact in any detrimental way in powdered form when stored together?
