[Histonet] Acidic tap water and automated H&E

From:"Greg Dobbin"

Hi Folks,
It seems we have acidic tap water causing our H&E's to stain purple
rather than blue.  We have the tap water plumbed into the automatic
stainer. Is there a cheap solution here?  I am thinking I could add slow
dissolving calcium carbonate to the tap water wash buckets to gently
raise the pH, but the only source of calcium carbonate that I can come
up with that is not in powder form, is pellet lime for lawn
applications. I'm not ready to go out and buy a bag of pellet lime just
yet.  Any other suggestions or thoughts? Surely this is not a new
Thanks for listening/reading.
