    D-76 requires hot water, forget the exact temp. It will say on the package.

    Ilford's ID-11, a D-76 look alike, needs 40C / 104F so hot tap water depending on your set up at home may work.

    The temp needed to be heated to is 122F to 131F, somewere in that range, also distilled water is a hell lot better than tap water for mixing any chemistry, especially developer. Tap water has many minerals in it, whereas distilled has none.

    Can you mix a stronger solution and then cool it off quickly with cooler water to reach the proper concentration?

    You could, however it's not really an advantage.

    When I used deep tanks and ID-11/D76 we always noticed the first few films in a new batch lacked the quality of the later films, first fresh D76 hasn't had time to equilibilise which takes a few hours, and second later films benefit from the slight build up in bromide and other pocessing by-products once a few films have been processed. The Highest quality from full strength ID-11/D76 is when used replenished, followed by using at 1+2.

    Remember these developers were designed for replenishment from the outset.

Can i get a legitimate explanation why this 24 hour rule would help the developer in whatever aspect rather than using as soon as it cools? Thanks.
    Since you used the word "legitimate", I'd say Kodak and Ilford are probably the most legitimate sources for D-76/ID-11. Follow their mixing/processing directions. I don't think either company indicates any kind of "stabilization" period is needed after mixing.

    Michael:

    IIRC, the package directions themselves on D-76 recommend waiting 24 hours after mixing.

    The problem you describe here is typical of replenished systems, but not one shot systems, there is no build up of anything with one shot.

    As to equalizing, what reactions are going on?

    Ilford's info does not.

    I haven't been able to find a copy of the D76 mixing instructions.

    Hi Matt, I don't have a package handy but I'd be pretty surprised if it said that. It isn't in the tech publication either.

    It depends on your water supply, not all dissolved minerals are detrimental. Kodak designed their chemicals and development times for "normal" tap water whatever that is. They do not specifically recommend distilled water because it might actually change the developer's performance slightly. I would be more concerned with the water used with the Photo-Flo, which at least ought to be filtered - distilled might be even better.
