    Ok. So I got a wrong idea how it is diluted.

    There's no wrong way, as long as your end result is 1 part dev and 31 parts water.

    You could do it in 5 steps and assuming your measurements were all correct still come out just fine.

    If this stuff is anything like HC-110 it doesn't "go off" for a long time. Even the bottle itself says "Expiration: INDEFINITE" so I'm sure you will be fine.

    Stone is correct about the dilution procedure.

    However, for clarity, HC-110 (and I assume Ilfotec-HC) is very long lived for so long as no water has been added to the concentrate.

    Once you start diluting the concentrate, the resulting stock or working solution is relatively short-lived.

    What I thought is that I can dilute 1+3 from the bottle enough to have 1 litter diluted concentration. Then I can re-dilute (or dilute the diluted concentration) 1+31 to develop the negative. Is this right?

    It means that I would use less developer than diluting it 1+31 straight from the bottle to develop.

    Therefore the bottle (or the syrup) will last longer in my stock. Or take longer to "run out".

    Did I get it right?

    Sorry, but no.

    If you first dilute 1 + 3, you end up with an intermediate "stock" solution.

    To turn that stock solution into something you can work with - a "working solution" - you need to further dilute it 1 + 7 (1 part stock plus 7 parts water).

    The end result is working strength developer made up of 1 part concentrate plus 31 parts water - 1 + 31.

    If you were to dilute the stock solution 1 + 31, there wouldn't be enough developer in the result to work properly.
