    Is this use of Photoflow problematic?

    When processing 35mm rather than mixing individual batches of Photoflow per reel/tank, I 've mixed a small Tupperware container with a lid, and seesaw the film strip through it before hanging to dry. The film is well washed.

    I began thinking this may not be the most advisable method if there is some chance that there is any chance of fungal growth, etc. in the tub over time. Any comments or recommendations for or against this approach?

    Eventually the photo flo working solution does start to support life.

    For a given weekend or two I'd expect it to be fine, beyond that ... ?

    Personally, after my first experience with photo flo as a biology project I decided to dump the working solution after every session.

    It's fine for a few days but the photoflo will start growing algae after a bit. I make up about 1L, use it for a session (10 rolls?) and toss it.

    That's what I do too, and the same bottle of wetting agent has lasted for years, so the per film cost is ridiculously low.

    Some wash aids have alcohol in them, like Sprint End Run. I should mix some of that and see how long before stuff starts to grow in it.

    I use a drop or two in a lasagna dish for 4X5 negs on a one time only basis. I wouldn't use it in a plastic tank or stainless reels or anywhere developers or fixing baths are used, I don't think a container will ever be clean enough after Photoflow.

    In another thread on Photoflows' use, Photo Engineer said if you use enough to cause a foam, you're using too much.

    If you constantly use the same wetting agent, it will accumulate contaminants like chemicals from fixer and as others have said, algae. Just add a few drops to the final wash, just enough to form a few bubbles, agitate and dump. Why folk try and save a nth of a penny on wetting agent is beyond me - I bought my 1 L bottle of Ilfotol in 2007 and I'm still using it!

    Cheers,

    I use Edwal LFN. I put 1 or 3 drops per pint of water then toss it after a film processing session.
