I have now performed "my last experiment" concerning Tetenal C-41and Kodak Ektar 100, i.e. I have in this case developed one (1) 120 film Ektar 100 in the same Tetenal C-41discussed above: i.e. Jobo CPE-2,Tank 2553, developing temperature 38C . (100F), rotating speed 2 (fast). Washing in something like 36C after developing and beach fix, the film has put in a bath with some drops and Kodak Fhoto-Flo, (some drops of Kodak Photo-Flo also in water used in bath for 2 minutes before starting the developer) and hanged to dry:

Result: NOT A SINGLE SIGN OF THESE FLAKS!!!!.

I have now put this dry and clean film into the stabilizer bath (roughly 20C) which today was filtered.
Tomorrow we will see if something has happened. But in any case: no "flakes" on the film, dry and clean, before the stabilizing bath!!!
