    XTOL is sensitive to very high Iron content in the water

    Depending on where you live, the Iron content can be too high for it cope with.

    Reverse Osmosis water is an acceptable alternative to De-Ionised.

    As posted my Fanshaw - Mineral Water sold in almost every supermarket is another suitable alternative - look for one with a low mineral content

    Don’t use condensate from your AC system – its full of nasties :o

    I mix all stock solutions with deionised water, and most working (single use) with tap water. Some working sols require deionised for optimum results. If your tap water is fairly putre then a faucet filter is sufficient to supply your needs.

    For XTOL, yes. The reason is dissolved iron. If you have cast iron pipes in the water supply chain, you'll have some amount of dissolved iron in the water. Iron has been implicated in "early XTOL death" where the developer suddenly quits working. Mixing with steam distilled water seems to solve this particular problem.

    I don't know if reverse osmosis would get the iron out. But steam distillation seems to do the trick.

    Bruce, your quite wrong, these and the jug filters work remarkably well as long as you realise they are designed for smaller volumes of water, they are ion-exchange filters so will take most of the dissolved minerals out of hard tap water, certainly sufficient fo processing uses.

    My filter takes out the dissolved Iron, although it's a cheap brand compared to a Britax. I also have a lab de-ioniser which doesn't get used as the small filters are more than adequate.

    I always use distilled water when mixing up Xtol or diluting it. The expense is not that bad, and it's a sensible precaution. How many people actually know the iron content of their water and are prepared to evaluate it?

    Another vote for the Britax type system.

    I use the jug and sometimes prepare about 10 - 15 litres in advance of my film processing, then store it in a large clean water carrier.

    Distilled water is not expensive, at least in the USA. $1 a gallon. I'm poor and even I can afford that to avoid risk of my photos out coming out right.
