    I am aware chemistry contamination BACKWARDS can be problematic.... (when trays are arranged in dev, stop, fix1, fix2, HCA order)

    An unfortunate darkroom incident caused a small amount of Kodak HCA working solution, perhaps 10cc or so to go into fix2 consisting of a liter of 1:4 solution of Ilford Rapid Fix. I am assuming, this isn't going to cause any issues. Would someone please confirm?

    Thank you.

    It will be just fine. You just added a bit more sod sulfite and metabisulfite to the fixer than it already contained. No big deal.

    I agree with tkamiya. The fixer should be just fine. If you're really that concerned, then leave your film/paper in the fixer slightly longer.

    HCA contains nothing that will harm fixer (just sudium sulfite, sodium bisulfite, EDTA-sodium, and sodium citrate, from what I've seen), so in this case the fixer will be OK. But the previous poster is right - when in doubt, throw it out.

    How about when in doubt, ask on APUG?
