Silver in fixer.

[Guest]

I have just been looking at my 120 negs done in the last few days and I have what I can only think is silver from my fixer on the negs. I filtered the fixer with coffee filters last week, I think the silver inside the bottle has fallen off and got onto this lot of negs.
What do you lads do about filtering the fixer you use. Also is there a way of getting the silver off the bad negs.
I have also encountered minute areas where the emulsion has even fallen of the negs, anyone else found this problem.

I am using FP4 and the temp never get's over 70f.
Please explain what you mean here........

Permawash or some other hypo-clear, then a thorough clean water wash.

I wash the film for half an hour at the end but the silver has done the damage by the, do you filter the fixer ?

I use fixer only once for films and then rinse using the Ilford method.

DON'T use a hardening fixer (no reason, and washing times are ridiculously overextended) OR hypo clears (again, pointless) but equally DON'T overstretch your fixer. Ilford's recommendations (films per litre) have a generous safety margin, or use the test described in http://www.rogerandfrances.com/subscription/fixer exhaustion.html

Sources: Ilford, and any author who has the faintest idea of what he is talking about (Haist, Glafkides, Clerc and many more: I make no claims to be as knowledgeable as they).

Also, use thoroughly strained water for all processing stages: see http://www.rogerandfrances.com/subscription/mt paterson water filter.html
