I photo-flo my film in my reels in my tanks and don’t have an issue with foaming. If your photo-flo is foaming to the point it’s affecting film, you’re likely not diluting it properly.
If one uses PhotoFlo while the film is in the reels, the reels need to be scrubbed with hot water and a tooth brush or the film will start sticking to the reels.
