Thanks for asking that Sarah! I was just about to post the same question... I've just moved into my grandparents old house in rural New Brunswick, and am planning on converting the basement bathroom into a darkroom... It too runs on a septic system...
I've worked with cafenol for developer and usually use vinegar for my stop. My main question then is for fix and hypo-clear... Are there any recipes for eco-friendly fix or hypo-clear?... although I supposed... the problem may not be so much the chemical itself, as the silver.... but any eco-friendly suggestions would be much appreciated! I can't wait to check out the links already shared!
