Help! I am developing Ilford FP4 8x10 negs with XTOL 1+1. Using Kodak Professional fixer, and Kodak photo flo. I keep getting running stains that run down different parts of the negative. I have tried not using photo flo, reducing the amount of photo flo, or just water to rinse. Nothing seems to work. The area that gets the scum on it even looks effected on the other side of the negative. Happens on either side of negative. Even tried rewetting negative and rubbing scum off, but stays on.
Doesn't occur on all negs, but more than 50% of the time.
Any suggestions???
