    Has there been a change in your water supply?

    Not that I am aware of.

    I am using distilled water for the presoak and to mix with the xtol.

    Then it is all tap water. The stop and final wash included.

    But the fix is also made with either bottled water or distilled water.

    David,

    From the look of your negatives it appears that you have the same problem I had with Paterson reels some time ago. I know you have washed your reels, but my problem went away after I washed and scrubbed my reels and tanks in hot water and regular washing-up liquid.

    I don't know what equipment you are using, but might be worth a check. Just a thought

    David;

    It is not a camera problem as the density is lower and extends into the edge markings. It is not a coating defect as far as I can see. My only guess would be as Bill said earlier about bubbles or my idea that it may be the reels, but I have no idea. I would have gone with the bubble theory, but the marks are so large. Sorry.

    Two different cameras. Two different films.

    Same tank and same reels.

    David,

    This may be a longshot but I once mixed developer in container that was thoroughly washed and cleaned but once contained ethylene glycol. Apparently the chemical leached out of the plastic and contaminated the developer in such a way that it caused striations across the film that were about 1/2" long and separated by about 1/2". They looked like long versions of your problem.

    I got some brown glass jugs and have never seen the problem again.

    I would mix a fresh batch of developer in case something strange got tossed in when you prepared the developer, perhaps an oily substance got into the developer and floats to the top and sticks to the film, preventing development.

    Thanks Fred. I will try that.

    I have separate, 1 liter plastic bottles that I use for only xtol. Nothing else has ever been in them.

    This is also my second batch of xtol, mixed with distilled water, and the problems continue.

    Maybe I need to try another brand of water?

    One cleaning agent I've found to be *very useful* in cleaning JOBO reels is toothpaste - ordinary toothpaste, with its mild abrasive. I've used Tom's of Maine, but most any other will do.

    Also good for removing minor stains from Tilly hats.
