After I moved to Spain, I was shooting nothing (professionally) but Kodachrome; however, for a year or two I did attempt to keep up with my black/white work if only for my own interest and enjoyment.
I was not using 120 film for that 'private' stuff, only 135 format. As I knew that I wasn't going to be doing very much of it, I decided against using D76 and keeping a gallon flask of stock solution in the cupboard because it was going to rot well before it got used. So, I turned my attention to the two Neofin developers, red and blue, which came as one-shot vials. This answered the problem well, but did nothing to help with the real bitch, which was the bad water supply. I had fitted filters to the supply, but they were incapable of preventing tiny grains of sediment getting through and from sticking to the film, despite using wetting agent after the wash as normal. In the end, it simply stoppd being a pleasure, so I closed the darkroom part of the office. I never made another black/white print that way.
How fortunate we were in that regard living in the Clyde area of Scotland; you could even use tap water to top up your car batteries.
