    Yeah, diluted with good old adelaide tap water, SAWater's finest. Can't remember if it went through the Puratap or not (or if it did, if that would remove the iron anyway?)
    When I made it I had half a gooniebag of the springwater, although I think I had to add in some normal tap water at the time.
    I've had a look through my scans, earliest scan I can find with Xtol on it (yes, I name my scans with the developer for reference) was at the end of May.
    So it definitely lasted May-Oct, which is 6 months, and died somewhere before yesterday, 8 1/2 months or so. Given that it was in the airtight gooniebag, and always used one-shot and tipped out (never replenished), I wouldn't have thought 9 months was out of the question.
    I didn't know about iron sensitivity, nor about the fact that it 'just stops' or I probably would have clip-tested (I shall in future).
    So I'll just take it as a very bullet-dodged lesson with no big loss (they were $2/roll expired, the film that worked in the microphen had some of my holiday to canberra, the two I lost were all shot at the cricket, I'm pretty sure there were no good shots in them which is why i'd been putting off developing them).
    An awful lot of electrons were terribly inconvenienced in the making of this post.

    f/64 and be there.

    The iron problem is stated here http://www.apug.org/forums/forum37/24281-xtol-4.html . Look at post #34.

    I actually distil my own water. The stuff you buy in the drug stores is probably just filtered. Judging by the sludge left behind at the bottom of my distiller, I trust mine.

    When I make my xtol (mytol), it uses salicytic acid to combat the iron problem. There is stuff in the original xtol too, but time will usually kill the 5l of xtol. I think it was a big mistake when Kodak removed the 1l from the shelves.

    But like I said in a previous post, replenished did not spoil for me. It may be an option if throwing the unused stuff makes your blood curdle. I preferred the look of replenished anyway.

    While Xtol contains DTPA, Adelaide water contains so much iron it's not funny. Until a couple of decades ago, there used to be two ports that the Royal Navy wouldn't take on water: Aden and Adelaide.

    We now have new processing plants but in about half of Adelaide, the water tastes disgusting unless charcoal filtered and if there's been a lot of flow, I get little 0.3mm brown (iron oxide) chunks coming out of the tap.

    Happily, there are some very clean freshwater springs nearby with low iron content and we can buy 10L bags of good water for about $3.50 and that works fine for making up xtol.

    I have been told that the format of 1L bag of X-Tol was not as tighly sealed - therefore not reliable enough - as it is the case with the 5L one. I don't believe much this explanation; I rather think the 5L is kept alive for industrial use, the regular amateur not being the target, marketing wise...

    Think of it like this: people buying the 1l kit are very low volume users, and are the most likely ones to run into problems with expired/inactive Xtol, and will most likely scream about their bad experiences in multiple internet forums. So we are looking at a product (Xtol 1l kit) which creates little revenue and a great risk for the reputation of the product. Any reasonable manager would cancel such a product as quickly as possible.

    It is most probably the case.

    I was one of the early users of Xtol. Still have one 1L kit unopened - I think it was offered as a 2x1L kit at the time.

    Xtol dead before mixing?

    I mixed up a 5L batch of Xtol on 18th December 2013 from powder that had an expiry date of December 2013 on the packet. The first roll I put through the mix this evening (15th January 2014) is completely clear, no edge markings, zero. It's my fault for not testing the chemistry first on some junk film because I lost some nice shots on that roll.

    What are your experiences with the expiry dates on the powder? If the packet is factory sealed shouldn't it be okay? Lesson learnt the hard way.

    That would rank up there with highly unusual. Was the powder discoloured or clumpy?
