I have read in a few places about using C41 fix to fix B&W films and papers.

I am happy with using TF-3 Alkaline Fix for my films but am interested in trying Kodak Flexicolor C41 Fix for my B&W papers. I can buy a 25-Litre pack of fixer/replenisher for little money but just want to know if this is the correct stuff or do I have to look for the Fixer on its own?

TIA Eddie
