The red colour is a dye in the B&W emulsion nothing to do with what the tanks been used for before. Tmax films have the strongest colour, fix a bit longer than usual which is necessary with Tmax films anyway and extend the wash the colour does wash out. Doesn't need to be running water just leave the film soaking.

Pretty much what I was going to post. I use the same Nikkor tanks and Jobo Expert Drums for b/w and color. No issues with either if you simply rinse them out after using.

I don't put Stabilizer or Final Rinse in my Jobo tank, however. I believe I picked up that practice at Jobo's recommendation.
