    Jeff,

    If you haven't, see Greg's thread on film washing tests (I believe it's sticky). I would not recommend a three-minute wash time, no matter how many fill-and-dump cycles you had... And, if you don't use a hypo-clearing agent, then 20 minutes is the absolute minimum (30 is a lot better!).

    Whatever you end up with to wash the film, I would recommend taking time from your darkroom chores to dump and refill a couple of times. When I was doing roll film, I used a tall Wat-Air set to very low flow and then dumped it and let it refill a couple of times during the wash. That way, you get the best of both worlds.

    Best,

    Doremus - you are talking here of acid fixers, yes? The formulary folks indicated to me that with TF4 or TF5, 8 minutes was adequate for film.

    Your development tank and a hose stuck into it.

    I could go the hose-stuck-into-the-reels route, but am curious of anyone knows of a washer that takes 4 inch reels?

    I do it by hand - least favorite part of the process.

    2 x 1 minute fill, agitate, dump
    1 x 2 minute with hypo clear, dump
    7 x 1 minute fill, agitate, dump

    So 10 total changes of water (inc hypo clear), 11 minutes total. Something which automates this would indeed be nice.
