    Who said my dropper was standardized? I measured it out when I did this and it works out to 1:300ish. My dropper does about 10 drops per milliliter.

    Interesting. I wonder why there is a difference. According to the MSDSs, both use very similar ingredients.

    I use Kodak's recommended dilution and never had an issue that can be attributed to Photo-flo.
    Develop, stop, fix.... wait.... where's my film?

    I use a small syringe to measure 2.5 mL Photo-Flo and add it to 500 mL of water.

    Thanks for the information. Good to know that for most the Kodak recommendation seems to work well.

    I'm not sure what the secret sauce is in lfn, but it doesn't foam up and is idiot proof which is a bonus for me

    I should add that in my previous apartment, the water was different and I used 1:200 with no problems.

    I used it at 1:200 (per the directions) for years with no problems. I then read so much about it working at bigger dilutions, that I generally go 1:400 now. Still works.

    But, In all fairness, I am a big believer and proponent of following the directions.

    I too have experienced water marks with ussing too much Photo-Flo. Only a drop or two are needed for each 250 ml. You need just enough to break the surface tension of the water. The problem seems to be with the anti-foaming agent that Kodak uses, a tallowate. As the name implies it is made from grease. The other active ingredient is Triton X-100.
