Ammonium thiosulfate (60%) 3/4 cup (200 ml)
Water to make 33 fl. oz (1 l)
Sodium metabisulfite 1 tsp (12.6 g)
Sodium sulfite (anh) 1 tsp (8.8 g)
I like the idea of premixing the dry and holding in film canisters.
I'll be using Arm & Hammer wash aid (Sodium sulfite - mono). Do you know if the increase from anh to mono is 15% (8.8 x 1.1765 = 10.4)? Any feelings for capacities with Fiber Base papers?
