Eddie's got the sodium thiosulfate name right, and probably meant sodium sulFITE for second chemical (I think, because sodium sulFATE is used for, among other things, possibly, high temperature/tropical developer recipes - see Anchell/Troop or research before self-diagnosing - I can't remember if it has some other effect on emulsions...or maybe that is it's sole purpose, to keep emulsion from tending toward dissolving at elevated temperature)?
