Well, after all these answers I want to try to use ID-13 and Kodak
D-85, for 2-3 mins with fils.
I have a matter with sodium bisulphite, ttah appears in D-85 formula.
I've not this substance available, can I replace it with somenthing
else? Is it really necessary?
Thanks, I'll let you know the results of my tests.

This is a self-answer! I've found that sodium sulphite can be used
instead of bisulphite. Considering the small amount in D-85 and making
the conversion using molecular weights I think to try this way.

I do not know how critical pH is in this solution, but if it matters,
sodium bisulphite is more acid than sodium sulphite.

D-85 has boric acid in formula, maybe it is better to add a very small
amount of acetic acid to decrease pH, even if I'm not sure it is
really necessary. Anyway, I'll try ID-13 first, if I'm lucky this
works well.

A good tip, thanks.
