    Really need distilled water?

    Hi all,
    I bought one of these to try out:

    http://www.firstcall-photographic.co...-devfix-iso-25

    In the development instructions, it is very firm about using distilled water during development. I've always had my brother develop just using tap water and I'm happy with the results. Is this film special in some way, and really needs the distilled water?

    Thanks

    Garry

    The qualities of tap water vary and can effect things.

    Distilled water takes out those variables.

    It's not expensive so for the first trial I'd suggest distilled.

    Will it really matter? You'll never know unless you try it both ways.

    I used to use distilled water for everything, mostly because I got it for free from work.

    Now the only thing I used distilled for is mixing up Xtol and final rinse.
    f/22 and be there.

    As mentioned above, depends greatly on your water source. I use tap where I am as it is generally of good quality and has not yet posed any problems for me.
    Thank you.

    If you are concerned about your tap water, run it through a filter. Either a pitcher style, or a faucet mount, will help improve the quality of water you use. I use distilled only for mixing chems to stock strength, after that I use tap water. My final rinse is distilled water with LFN and isopropyl alcohol blend, never any streaks or spots, and rapid dry.

    I would agree with Mark that using distilled water takes out any variables that may be in your tap water. I believe they are simply stating the optimal conditions for using their chemicals. I use filtered tap water and a distilled water rinse for spot free neg's. I believe filtered tap water is just fine, but that is just part of my methodology.

    Its a rinse aid made by Edwal, I like it better than photo-flo, personal preference. It calls for 1 drop per pint distilled water, or 2 drops tap water. It can also be added to developer to eliminate bubbles, cant do that with PF. Also, it doesn't gum up my reels like PF.

    I just use distilled water for the Ilfotol or Stabilizer step, the final one for better drying, less spotting hopefully. Once in a while when I have no aged room temperature water I'll use it for other wash/rinse steps too.

    It depends on where you live and what chemicals you're mixing up. Distilled water is more of a sure thing when mixing up chemicals. If you mix Photoflo with hard water, you may have spots. From my observations cities that draw water from rivers and lakes have better water for mixing photo chemicals than cities that use well water.
