On the subject of fixing Tmax films: Kodak, in its publication F-5, Kodak
Professional Black and White Films, states: "Your fixer will be exhausted
more rapidly with Tmax professional films than with other films.''

That suggests to me that Tmax is rougher on the fixer and that longer
fixing times can be expected. However, this should be of little concern and
is easily dealt with. Kodak recommends fixing any film for twice the time
it takes for an exposed, undeveloped length of film to turn clear in the
fixer you are using. Some suggest three times, to be safe. Unlike
development, fixing is a process carried to completion, and extending
beyond completion won't hurt things (within reason, of course).

In any event, if this is a problem or concern, you should perhaps switch to
a more powerful rapid-type fixer. Kodak and Ilford both make one. I prefer
two others: Heico's NH-5, and Sprint Systems' Record Rapid Fixer. The
latter designates a stronger, 8:2 dilution for film than paper, 9:1. 

The pink cast will, however, wash out in running water or in a solution of
hypo clearing agent.
