For Karie's query;

I have just a little input from a newbie.  I am researching stains and
fixatives for causes of error in one of my courses.  For the hematoxylin
precipitate attributed to inadequate filtration, I found a site that
discussed this, along with formalin pigment, mainly that sometimes
precipitate that is believed to come from the hematoxylin, actually can be
caused by other things.here is the site to check it out:

It may not be your filters.  Just a thought.
