FIXER D-I-Y TEST

I have made a fixer for film & paper a test but
first -- this is the recipe

1 lt. water with
ammonium hypo 300gr.
sodium hypo 200gr.
S. metebisulpite 40gr.
S. sulphate 40gr.
P. alum 05gr.

what would be the correct working solution ?????? 1 to 3???

What's the supposed point of this formula? It's an acidic hardening fixer (barely useful today), which mixes Sodium Thiosulfate with Ammonium Thiosulfate - you combine the high cost of Ammonium Thiosulfate with the poor capacity of Sodium Thiosulfate. It may be inspired by some older Fuji patents which suggested that combination but ultimately went nowhere.

If you insist in using this fixer, then I'd go for 1:2.5 for fixing films and 1:5 for fixing paper. Expect long fixing and washing times.

I agree with @Rudeofus; this formula is essentially a waste of perfectly good ammonium thiosulfate.
