More than two minutes in fixer makes it difficult to wash out. If you used the old nomenclature your stock would have been 1:3 and Dilution B would have been 1:31 from concentrate. Note, I never save fixer for extended periods of time like some do; I try to match the amount and dilution of my fixer to the amount of film I have for a specific batch. If you over fix, it take a lot more washing to get the fixer out of the Paper, Fiber base. He said this in another post also, I asked why, and never got a response. This must be well know.
If the stain is slight, it will not affect image stability, negative contrast, or printing times. Clearing the pink is not the purpose of the fix, so separate the two functions in your mind. Be sure the developer is at 68°F 20°C. Some variable was making it work sometimes, and not other times. I just bought a bottle of Ilford Rapid Fixer.

How long is long enough - 6 months, 2 years or 100 years? To increase or decrease film contrast or to use a different developer temperature, find the adjustment factor in the table. Minimize safelight exposure to avoid unwanted quality changes.
Use this solution as the normal working solution or replenisher. I may be fixing more than needed, but am assured that my negs will stand the test of time. Important: Your fixer will be exhausted more rapidly with this film than with other films. I wasn't doing much shooting lately, my fixer was sitting in the bottle for nearly a month.

Haines from The Gold Standard for Film Fixer This is a great standard fixer for any development process I can think of. As to fixing fibre based papers longer than necessary it simply makes it more difficult to get a good wash. If you want to mix up some dilute fixer, mix it immediately prior to using it.
This happens due to transformation of the complex into fine particles of silver sulfide. One needs to first consider that film or paper , as it enters the fixer, is already wet. Ilford says this will fix about 600 rolls of 120 film at 1:4 dilution. Provide initial agitation of 5 to 7 inversion cycles in 5 seconds, i. To enhance D-max areas and protect the image, dilute toner 1:20 or 1:40. This is a high-speed panchromatic film that features fine grain, high sharpness, and high resolving power. Replenishment Rates Developer--Because most film loads will consist of a variety of film types, use an average replenishment rate of 0.
However, I have stretched out my stock solution for up to 6 months. I found that in order to fix properly, fresh fixer works best. Fixing for to long period and you lost shadow details. I've got several fixing regimes based on the number of sheets I have to develop so I can toss the fix after the session. See instructions packaged with Paper. It's a hypo-based fixer, with some other ingredients to stabilize it and make it fix more reliably.
