For some reason, I haven't found any relevant information in any of the numerous fixer reuse threads, whether here or elsewhere, so I feel obliged to ask. I got a bottle of Moersch ATS fixer in the post today, and I am uncertain about the procedure. With Ilford Rapid Fix I reuse the 1:5 solution about 20 times with no ill effects (unless we're talking Kodak TMX; the solution capacity gets trimmed down quite a bit in that case). When I started using Pyrocat like crazy, I took the advice to avoid acidic fixers to heart; my standard procedure would be a really long wash instead of a stop bath followed by a long dip in sodium thiosulphate solution, 125 g per 0.5 l, which would then get discarded.
So, as I've said, there are lots and lots of threads out there about reusing acidic fixers. Alkaline? Nothing. Or at least, nothing that I could find.
Thus, the question is (as if it wasn't obvious enough already): is alkaline fixer reusable at all, and, if so, how many times can I safely reuse it? Do I extend the fixing time after reuse? Any firsthand experience, anyone?
