>>3466086>>3466087 I use Tetenal, on my 4th 2.5L kit. I get 30 rolls per L out of both their c41 and e6 kits. Currently on roll 33 with my current c41 chems and may do a few more rolls. Results seem perfect still.
Workflow is basically the instructions. Use a sous vide as pictured above and 2 aquarium thermometers (1 in the water bath to ensure temp is okay and 1 in sink for rinses between chemicals).
