    170 ml in a Jobo 2500 tank

    Hello board,
    I've read somewhere that the Jobo 2500 series tank can be used with a reduced amount of chemistry for processing 2 sheets at a time, but can't find a reliable source for this.
    Right now I'm using 270ml for 4 or 6 sheets and read that it can be reduced to 170 or 150ml. I'm testing the E6 Tetenal kit and would like to save some chems for the first test sheets.
    So the question is- is it safe to use this tank with 170 or 150ml of chemistry? I'm using the P speed now for my BW processing, is it necessary to adjust it for reduced load or color?
    Thanks in advance,
    Nicolas.

    I would try it for test sheets only; if it works, great, you have your answer.
    If it doesn't, you've ruined two sheets of unimportant film.

    Rotation or inversion development?

    It makes a big difference.

    The minimum solution table is here. Looks like you can only do 170ml with a 2513 and 35mm.
