Thanks for the info, Aggie. In the near future I will be improving my darkroom, adding proper ventilation is on the list. As of right now, my ventilation is an open window, with cardboard, blinds, and black out on top. It freshens the air, but isnt ideal...
Maybe when my darkroom is re-done I'll consider more chemicals, including bleach. I appreciate the info, though.

Jdef, Thanks for those links, they will be life-savers. As soon as I settle down on developer and bromide, etc... I'll test my filtration.

Thank you all again,
