I also have one of those wonderful waterless darkrooms!! (Think it's a WI thing??? ) I just started doing fiber, so I may not be the most knowledgable, but here is what I do... I develop, stop, fix; then I do a 5-10 min rinse in a large tub of water. Then into wash aid, then into a shallow tub of water (this is my holding bath) until I am done printing. Then I take move the prints from the holding bath to the tray I use to transfer things up to the bathroom where they get a leisurely soak in the tray in the tub. I change water 4 to 5 times in the tray & move everyone around so they don't get too cozy.
I don't know if this helps any, but what the hey!
