> Arista fix 1:9 2 minutes agitate 10 sec every 30 sec(posted 8058 days ago)I'm guessing this is a standard ammonium thiosulfate rapid fix; rapid fix is usually diluted 1:3 or 1:4 for film and a short fix time. I don't believe ammonium thiosulfate fix can be concentrated enough to get the same working strength at 1:9 or so.
So I suspect that your film wasn't fixed enough. Check the Arista docs to be sure, but I'll bet you'll need a stronger working solution for a two-minute fix or a longer fix time for the 1:9 dilution.
Also I'd suggest giving continuous agitation in the fixer.
One more thing: how to check fix time....
Take the film leader that you cut off, wet it in water a couple of minutes, then swish it around in fixer, timing how long it takes to become clear. Fix for three times the clearing time, giving continuous agitation.
