Even better, if you're going to tone FB prints, HE-1, an easy to make Hypo Eliminator, is easy to use. It was discouraged in the 1990s when it was discovered that a small amount of fixer left in the paper helped longevity, but proper toning does that even better. So, I print, single fix, quick rinse with running water, and into the washer with no water running. When I'm done printer, I mix up my toning baths, place the prints in the 2nd fixer, dump and refill the water from the washer, tone, brief hose rinse, he-1, and a short time in the print washer.
