[pure-silver] Re: Really really pink negatives

Hypoclear before washing?
When I was using HP5 I remember my hypo-clearing agent turned color (I can't remember which shade). But I used hypo clear after the first rinse, and then gave another rinse after that. Since I don't remember any color coming out during any other step but the rinse and hypo- clearing, I'm wondering if the hypo clear coming before the water is causing some type of reaction with the anti-halation layer. 

Just a wild guess.

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?
