Photographers' Formulary TF-4 Archival Rapid Fixer (Liquid) (1/2 Gallon, Make 8 Liters )

You can use Photographers' Formulary TF-4 Archival Rapid Fixer for Black & White Film and Paper to fix most modern black and white films and papers. However, when using it with T-Max film, this fixer will also remove the magenta stain characteristic of T-Max if you fix for 6 minutes.

Although it is best to take photo chemicals to a facility where they can be properly disposed of, most normal chemicals used in processing are no worse than household cleaners that are normally put down our drains. (Bleach, 409, etc.) So use reason and common sense: if you process 200 rolls at a time, dispose of the chemicals properly. If you are doing 3-4 rolls every week or so, you shouldn't worry and pouring them down the sink is fine.

Try shaking the bottle for longer before diluting (when you first get it in the mail). The fixer should be a little milky when first mixing, but soon turns clear after diluted and initial use. Careful not to use a solution that is either too diluted or too concentrated. Test your mixed solution with a small strip of unfixed film cut off when loading onto the film reel for development.

Yes, this is normal. Negatives processed in PMK will not look like negatives processed in typical developers like D-76, they will have a coloration to them that when you first see it can be a little alarming. But that is actually how they are supposed to look.
