Anyone ever used Kodak DK-15

Water temp in the summer can be about 78 degrees in Louisiana. Couldn't find any info on the web so I thought maybe I would ask y'all what your thoughts are.

I lived in Turkey for quite a dew years I just processed at the ambient water temperature which was 26-27ºC that's more than 78ºF, 27ºC is 80.6ºF. I never have an issue.

Most modern B&W films are well hardened to there's no need to use a tropical developer.

Cool, thanks for the response. I was looking through an old darkroom book and they had the recipe. Never knew it existed.

I did film in the tropics at 83-85 F all the time, I ended using high dilutions and lighter agitations, with no problems with a softer emulsion, but I wasn't using anything but Tmax's and Ilford, I would think the Foma/Arista might have more potential for that issue. FX-1 and Beutler's.

There was member who said that he developed his film at 100 F, way too hot for my taste, 80 to 90 should not be problem.

90f was common practice with Tmax 100 when it first came out. There was an article in the old Darkroom Techniques magazine about Tmax 100 at 90f degree.
