    BTW, T-Max R/S is a developer/replenisher too.

    I've used control strips in the past, but I learnt a long time ago how to spot when a replenished developer is changing/deteriorating.

    With Xtol Kodak's recommended replenishment rate is more than is actually needed so includes a generous safety factor and I've never found any noticeable varirations beteween negatives and they always print consistently.

    I've been experimenting recently with replenishing HC-110 and have discovered one practical advantage of a replenishment regime that hadn't occurred to me before-hand.

    With replenishment I'm always developing film in developer that is already at a stable room temperature. I don't have to worry about getting the diluting water to a particular temperature, I only need to measure the temperature of the room temperature liquid, and adjust my development time accordingly.

    Of course I do live in one of the most temperate climates in the world - my opinion might be different if I was travelling back and forth between, as an example, Turkey and the United Kingdom .

    My problem is that I don't have the ability to put that much film through it so I end up starting over with a new working solution every 6 months or so. I work with a 2 liter working solution and replenish with the remaining 3 liters.

    The question I have is;
    When I mix a new batch of stock solution can I season it with the old working solution? If so how much of the old working solution should I use.

    The Xtol tech sheet gives seasoning instructions, easiest is probably kodak E-6 First Developer Starter which is inexpensive.

    This is a major advantage that many overlook, in the UK I simply stick the bottles of dev, stop & fix in a bowl of warm water in the winter (no central heating ) which is very quick.

    I used to process while travelling in the UK and would just take the bottles in the car, the no mixing or critical measuremnts of volumes meant I could process easily when camping on longer trips.

    In Turkey I've not been using Xtol, however the ambient Summer temperature where I store chemistry is very stable and I just process to the water temperature which is the same so there wouldn't be any issues.

    I use replenished XTOL with a Jobo 1540 tank for 35mm and 120 film and a Jobo 3010 Expert Drum for 4"x5" film. I also use replenished XTOL in steel tanks with Hewes reels for single rolls of 35mm and 120 film for convenience rather oxidation.
