Since it is stated that Efke 25 is a classic emulsion and that it is
fragile when wet, I wonder if a chrome alum stopbath is warranted? I
used chrome alum years ago and it made the emulsion tough as nails.

Efke 25 is really fragile when it's wet.
BTW, I've "discovered" a really lovely way to develop Efke 25. Just
use Rodinal 1:100 with a 30 sec water rinse or so, then no agitation at
all for 25 min at 68 degrees. Try it and tell me what you think. I can
use the 25 min for all sorts of things and the Efke has this really
beautiful "edginess" to it when developed this way. No wierdness at all
in several rolls and my best results with this film by far.
