The developer was HC110 diluted 1 to 46 from concentrate and agitation was 15 secs every two minutes, film was Tri-X shot at ASA 200. Exposures were right on.
As for my water, I have a water softening system so it is highly filtered. If there wasn't any, the water would stain the porcelien fixtures, it's so hard.
This was just a freak occurance. I cannot remember this ever happening in the past and I cannot remember the last time I screwed up the development this badly. The next two batches of film came out just fine which were shot on the same day.
I did have my water checked last year, with samples taken before, and after the filter. No abnormalities came up, but I will recheck the report for acidity.
