Thanks, Liam. Your remarks are encouraging. I did add citric acid to the Ag Nitrate (high humidity formulae). And I use deionized water for the first "salt rinse" in the development process, then went straight to tap water which, being city water, most likely is oxygenated, halogenated, etc. It is raining so frequently here now that I could easily collect rain water and give that a try (Fortunately I live in an area where the air is relatively pollution free.). My final rinse after the hypo-clearing was 20 min in running tap water. Maybe I can end with a final soak in deionized to see if that helps.

Thanks again!
