Can anyone tell me how stable this formula is. It is part "B" of a Diafine clone formula. From the APUG site.
Bath #2 -- [3 minutes spinning BTZS tubes]
Sodium Sulphite 32.5 gms
Potassium Carbonate 20 gms
Potassium Bromide 1 gm.
EDTA 1 gm
Water to make 500 ml
I'm interested to know if Potassium Carbonate has a longer or shorter working life in this formula than Sodium Carbonate.
