Fixer is heavier than water and will tend to sink unless the wash water
is kept moving.

My process is pretty simple, but based on the recommendations by Gordon 
Hutchings in The Book of Pyro.  (I don't claim to have the knowledge of 
chemistry that is definitely had by some on this list.)

I develop normally.  I use a 60-second running water wash (at developer 
temperature, usually 20 degrees), a 3- to 6-minute fix in Photographer's

Formulary TF-4 fixer (longer for T-grain emulsions and with less fresh 
fixer), and a 15-minute wash in developer-temperature water (gently 
running).  I empty out the tank a few times during the wash (maybe 4-5 
times), although I understand that fixer is less dense than water and 
floats out anyway.

The wash exceeds the recommendations, but it makes me feel better.
