Response to Getting awful photo-flo stains and water marks on "New Improved" Delta 400 120

I generally recommend that the wetting agent be mixed rather dilute; in the case of Photo-Flo, use a ratio of 1+400-500, which is roughly half the strength that Kodak recommmends. The same ratio is appropriate with ILFOTOL Wetting Agent. Also, use distilled water, and a fairly fresh solution. Dry at room temperature; a warm drier will cause the film to dry before the wetting agent has time to run off, which will leave the stains you are seeing.
