    just to muddy the waters, I use Kodak Rapid Fix without the hardener and I have seen no problems with reduced stain with PMK or Pyrocat HD. When I was using PMK and shooting Ilford films (mainly HP5+) I tray developed everything and I used a pre-soak for about 2 min. I also added about 4 or 5 drops of LFN to the pre-soak. Theory was Ilford adds some photo flo substance (or so I was told) to the film emulsion and I would be washing it out and I also thought it might help keep the film from sticking together.

    With Pyrocat HD I am using a rotory style drum and motor base and I pre-soak for 5 min using Jobo's methodology. Same Fix no loss of stain. go figure.

    You also don't mention the volume of developer you are using. Sandy would be he expert here, but I think you would need a pretty large quantity of 1:1:100 to develop 5 8x10 sheets of film.

    Good luck with this.

    This came up just a few days ago on another thread. All of my own work with rotary processing is based on the use of 250 ml of the 1:1:100 dilution. That would be 1250 ml to develop five sheets of 8X10 film.

    If you use the 2:2:100 dilution you can use slightly less. In fact, quite a bit less. For example, I have developed 20X24" film using as little as 500 ml of the 2:2:100 dilution, even though the minimum amount as suggested above would have suggested the use of about 1500 ml of solution.

    I use 500 ml of pyrocat for 4 4x5's or 2 5x7's or 1 8x10 but only because the math is much simpler and I am not a rocket scientist.
