Andy, I couldn't help but notice that you used what looked like a concertina plastic container for your Xtol. This type of container ,as you will know, seems to get pretty well universal condemnation on Photrio for (a) being air permeable and (b) very difficult to clean the insides
Can I ask: Have you had any such problems in respect of (a) or (b) above with that container? Maybe you have a later version of the concertina type of container that isn't air-permeable and/or both issues are in fact exaggerated anyway?
Thanks
