Anyone have any experience using Peter Hogan's alkaline stop bath? I'd like to use this for film development with TF5 fixer (which I believe is a neutral fix). The reason I would like to use the alkaline stop is it seems to be an ideal way around the "no-acid stop, water stop only" warnings for processing of film in staining/tanning developers. I hate using a water rinse to stop development. It requires a lot more volume than a stop bath, which complicates temperature control. Seems like Hogan's formula is pretty much the only commercially available alkaline fix on the market. Not sure what's in it.
