Thank you Richard for your reply. So if the second bath improves capacity from 4 to 10 times, this means with 2, 1 gallon baths, I could expect to do 40 8x10's as opposed to the single baths 10. And perhaps a bit more. Then I would use the 1+9 selenium toner and place a drop on a rebate area of the (washed) print and check for stain say after 2 minutes? And if I saw a stain, I would re-fix?
