If it is milky or cloudy, it has not even cleared, let alone properly fixed. Don't worry. You can refix it. Wet it with water first, and just put it through another fixer bath.
Do you know how to do a leader test? Even with freshly mixed fixer, my fix times for T-max when using this test and tripling the clear time are about 9-10 minutes. Without doing the test, I'd use 8 minutes as a standard time. That should cover you. I do triple the clear time, but only double is really necessary. With fresh fixer, my clearing time for T-Max is usually about three minutes (using the method with the reference drop placed on the leader first). By comparison, HP5 and such clear in under a minute for me in fresh fixer.
Don't worry about the pink color. It will not reduce your print quality IME. (Do worry about the uncleared silver, though.) The longer the film is wet, the more dye comes out, so if it bothers you, try using a longer process. Try a one minute post-fixer rinse, 3 to 5 minutes in Hypo Clearing Agent with constant agitation, another one minute post-HCA rinse, and then a ten minute wash. You can also do a pre-development soak, which will remove a large amount of the dye up front.
