A quick darkroom question, what do you do with your used fixer? From what I understand developer and stop are pretty non-toxic but fixer is full of of silver and not all that great for flushing into the sewer/river. At some point I learned to throw it into a tub with some steel wool which somehow takes the silver out of the solution, making the liquid safe to dump (leaving a nice sludge of silver in the tub to be recycled at some later date).
Now that I've been developing and printing a bit more the tub is filling up faster and I'm wondering if the theory behind this is sound or if I'm still dumping something I shouldn't down the drain.. Any thoughts on what to do or whether the steel wool method is affective are greatly appreciated....thanks.
