[pure-silver] Really really pink negatives

This week I had a student in my darkroom class develop her first roll of Ilford 
HP5 120 film.  The film came out with a vivid pink base.  The negatives were 
developed ok and seemed to be fixed - at least they had cleared.  She used 
Kodafix for 5 minutes. The fixer had been around for awhile, but, but I tested 
it first with a scrap of film, which cleared in a couple of minutes.  She also 
used Hypoclear, before washing the film with the Ilford method of 5, 10, 15, 20 
and 25 inversions and water changes.  I've used these methods for years and am 
used to a touch of pink or lavender with Tri-x, but this shade of pink was 
about equivalent to an Ilford #3 Multigrade filter.  What's the problem here?  
Could it be the fixer?
