Is this use of Photoflow problematic?
Yes. I now use a large plastic tub and remove film from the reel before putting it into the photoflo solution. I originally used Ilfotol in the Paterson tank with no problems. I bought Photoflo last year when I couldn't get Ilfotol. I've had foaming problems ever since, despite thoroughly cleaning everything after each session (I have always done that). I now use the separate tub, but my tanks still foam! I wonder if the Photoflo formula changed at some point in the recent past? Alex.
