I'm getting strange patches on film negative. Sometimes they are very big, but they also seem to appear along the border of the film.
I've just CLAed my camera. MY fixer is very recent so I'm not sure what the problem is.

When we develop film, we must take care that the film is properly wound on the developing spool. This is an example of improper loading of the spool. On the reel, the film is coiled so that it can be process using only a small light-tight tank. Improper windings allow the film to touch. Film in close contact will stick together. Once wet, the gelatin that coats both sides of the film sticks firmly preventing fluids from penetrating. You can attempt to mitigate by swishing the film in fixer. This will clear the opaque areas but likely the developer was unable to infuse thus those areas will be void of an image.
You need to sacrifice a roll or two, practicing loading the reel in the light and then again and again with your eyes closed. You can’t practice with a roll indefinitely as loading and unloading damages the natural curl of the film. In other words, you will need to sacrifice several rolls to truly get the hang of the loading procedure.
On another note: Once you finish the learning curve, save the film, it can be used to test the developer and fixer. Cut the films into snippets about 2 inches (50mm) long. You can swish one in a sauce cup of developer and in the light, watch it blacken. While not a perfect test of the developer, you will know that it is a developer and that it still has some life. You can also test the fixer to prove it’s alive. Swish a snippet in fixer and watch in the light as it changes from opaque to milky to clear. The correct fix time is always twice as long as it takes for the snippet to go transparent.

When I read title of the question I immediately pictured pink splotches. Been there, done that.

Yup. Some reels were easier to load than others. I liked the stainless steel spirals best. The ones with a ratchet where the film slides into the groove from the outer end had to be absolutely dry, and the film couldn't be too curled. I don't miss those days. Digits sensors are so much nicer, and better.
