    Of course not, soft water just contains less dissolved minerals than hard water.

    The heart disease study infered that something in hard water has a protective action on the heart. My post was directed to people who think that drinking distilled water or softened water is safer than drinking tap water.

    I am living in a country which all or most tap water are hard and un-drinkable, and difficult to get distilled water or it is costly, good that you told me about XTOL, so before i mix that developer i have to find where i can get distilled water.

    Use a Brita (TM) filter which can be installed on-line or via a water can.
    It is an anion- kation and carbon filter. One filter takes till max. 100 ltr. and the costs are around Eur. 4,-
    Xtol is sensitive for metal ions so are (low) contrast document developers. Problems from black spotts in the negative and stripes and drying marks are the problems of bad tap water till a shorten lifespan of the powder stock developer.

    The advantage of using Brita is it's almost direct available as perfect photo water. If you want to minimize the dissolved oxygen you can cook it.

    I hope that filter will do the job, is it good enough or still not on par? from the discussion here i still don't know if it is a good option to consider, it will not give pure distilled water, or am i wrong? also the question is, how good [or pure] water to be used for mixing?

    No only demi-water.
    Pure water they are making with Reversed Osmose, a UV lamp and a fine 10um carbon filter. Then it can be used for chemical analysis. For making it you need a Millipore MQ water system. Pretty expensive too.

    I have very good results with the Brita filter system. BTW nice for drinking too which is not a good idea with MQ water.

    I work in a local government department and we have a lab for health and environment, they have a machine to get distilled water, and they told me i can have a certain amount of the water, maybe free or very low price if they can't give it free, so i may try with them, but the problem is that i may get a distilled water from them but then i can't be sure it will be clean for long time, and mostly when i have to prepare or mix the developer on the box it is written i need to use high temp, so how i can be sure if i will use the water in heating or stored it will remain clean distilled water or free mostly of any particles.?!!! or it doesn't matter much and it will not be a big deal?

    I have thought about this and here is the way I look at it. If I use tap water at my house it comes from a well and the Ph changes depending on the time of year, amount of rain and whatever else I can't even imagine. Distiled water is water and water only, and if I buy the same brand all the time it should be the same within reason every time. I'm making photos for for myself so the tweak from tap water probably wouldn't mater to me, it might make a difference, but I probably won't care. Still I use distiled water to mix developer, I have enough trouble in my life, I don't want to worry if it was the water that messed me up on that roll of film.
