I don't replenish my working solution fix, but I do pour it back into a separate jar through a coffee filter. I'm not really sure if this has any effect on the byproducts in the fix, but I figured it wouldn't hurt.
You can "replenish" B+W fix too. "Replenishing" the fixer is essentially replacing it a small part at a time rather than replacing it all at once. It's also more consistent.

It makes me wonder why color fix takes 6.5 mins if the clearing time is 30 seconds...
Indeed, C-41 fixer can clear some B&W films in 30 seconds, but be aware that B&W films need far less fixing than color films. Silver that forms the image remains behind, and only the non image bearing silver halides need to be removed. Color films, both C-41 and E-6, have at least three (four?) separate layers of silver bearing emulsion, and all of the silver halides must be removed, placing a much heavier load on the fixer.

With the two bath method the OP would have
twice as much fix going bad. Used little or
not at all fixers do go bad.
If your volume is low and you've a few minutes
to spare the slow sodium form is the one to use.
It makes for a quick fix to mix. Spoon up a fresh
fix at processing time. That's what I do. Dan
i have read of people plating out the silver from their fixer using something like the silver magnet ( electroplating ) .
they use it as their first bath and use a fresh fixer as their 2nd bath ... they say they don't really have trouble ..
