    While mixing up a fresh batch of fixer, I inadvertently overfilled the mix tank to the 4 liter mark (rather than the 4 quart, or 3.8 liter mark.) I am not sure if this .2 liter over dilution is something to worry about or not, but on the other hand, I would hate to waste a fresh batch of fixer. Would it be possible to slightly increase the fix time to compensate? If so what knid of an increase in the standard 5-10 min fix bath duration would be recommended? Are there differences that I should be aware of between fixing film and/or paper. (This solution will be used primarily for fixing film.)

    Any advice or recommendations would be greatly appreciated. :sad:

    It doesn't matter in the least.

    Not enough to even consider.

    Some one still selling that stuff by the quart? Did
    you start with a quart of concentrate? If you did
    you're OK. You now have a very strong 1:3 fix.
    That's according to instructions. Right?

    I used to follow instructions. Now I misbehave
    most awfully. My film fix is used 1:24 and FB paper
    fix 1:36. Minimal solution volumes are used one-shot.
    All solutions fresh at start. With the fixers, film and
    paper, silver levels are at such a low level as to
    produce archival results with one fix.

    The only reason to use a very strong fix with film
    is because of film's tolerance of very high silver levels.
    Paper has less tolerance and so the suggested 1:7 or
    1:9 dilutions you see. Suggested 8 x 10 capacities
    are NOT intended to produce archival results. Dan
