    I saw that Feestyle is selling the Moersch fixer and was wondering what the difference was between it and TF-4. Can anyone elaborate on the differences between these two fixers?

    My guess, It is absent the large amount of
    Borax acid buffering found in or at bottom
    of a bottle of TF-4. Dan

    It looks like the Moersch is 20% more expensive...EC

    Moersch claims about double the capacity (150-200 rolls/l stock solution vs 80 rolls/l stock solution for TF-4), though, so maybe Moersch is about 25% less expensive. Your mileage may vary, of course.

    That could be. I do all my film one shot but reuse for paper. the only downside to TF4 is that I never seem to keep it shaken up enough and am a little afraid of my dilution consistency. I'll have to try the Moersch...Evan Clarke

    From what I've read that stuff at the bottom is borax
    and is included for the purpose of buffering against
    acid fixers. It is an alkaline fixer.

    Borax is not very soluble so the fix as it comes needs
    dilution. Is what I've read true? Dan

    TF-4 is mixed 1+3, so the 1 quart bottle makes a gallon and the gallon bottle makes four gallons. I always mix the whole bottle of TF-4, and there is no precipitate once mixed. The mixed solution lasts at least a year, so I don't see any reason not to mix the whole bottle, unless one doesn't have space for it. I usually buy the large bottle and keep it in a 5-gallon tank with a floating lid and a spigot.

    I'd be suspicious about claims of very high capacity. It may clear the 150th roll of film, but you may have problems with the silver thiosulfate complexes left in the film afterward. From what I read in Mees, fixer capacity is a pretty tricky thing, especially if you want archival permanence.

    Correction

    That should read; ... buffering against acid stops. Dan
