Thank you, Bill, for making the suggestion about replenishment. I have researched it in the past, and I understand that fixer replenishment only works in conjunction with a silver recovery option, as no amount of replenisher will remove the silver that is already in the fixer, unless you remove the solution itself—if this is incorrect, please let me know, as I am eager to know.

Having said that, I do use a silver recovery device (Silver Magnet from JNanian) to remove a good bit of the silver from the spent fixer. However, what is left gets taken away, as it is has been contaminated with stop bath carryover. I'd be happy to research replenishment too, but for now I am more focused on making a switch from acidic to a neutral one. I'll report my findings as to the pH stability when I have some data, for now I am using up the remainder of my acid fixer. Once that is under control, I would love to recycle/replenish my fixer, as anything I can reasonably do to minimise waste without creating something worse, is high on my agenda.
