I haven't used TF-4 for the same reason. But there is an alternative that should be available in Europe. I can even get it here in Australia.

Agfa make FX-Universal, primarily for colour processing. But it is an excellent slightly alkaline fixer for B&W film and paper. Agfa has started labelling it with B&W dilutions here, but they don't promote it for this use with much energy. (The same could be said for their promotion of their other excellent B&W products, I think)

They suggest 1+6 for film, PE paper and baryta paper,
and 1+5 for replenisher. Following are edited emails relating to its use for B&W (but I disagree with the need or desirability of acid stop bath because acid will make the fixer deteriorate and smell of SO2, but maybe not much):

You can buy alkaline fixer readymixed: Agfa Universal Fix (for Color C-41, but it works well).

I use Agfa Universal Fix (C-41) 1+4 for B&W films and the same for B&W paper. Substitute 20% of the volume with fresh fixer after each filmdeveloping.
Paper:I use 2 bath method and measure the silvercontent with Kodak silverteststripes.

The FX Universal can be used for Black & White papers at the following dilution,
1 + 7. You will need to use a stop bath between the developer and the Fixer. The
fixing time is the same as you would normally use for a normal, not rapid,
fixing bath.

Dear Trevor,
Thank you very much for your prompt reply. This is a very interesting product- the only competition is the TF-4 from Photographers Formulary (USA), but freight to Australia makes it completely unattractive price-wise. Agfa could promote FX-Universal better; alkaline fixers have some indispensable benefits.
Sorry to bother you again, but have you any info on its capacity for use with FB print material?
Kind regards...........John Stockdale (Melbourne)

We generally don't advetise the FX Universal for B & W as we have two other
fixers, MC & Agefix.
The FX Universal will do aproximately 1.5 sq m of Fibre based papers per litre.
Hope that you have success with it.
