I use a 60s water stop in a tray at least one size larger than the print. The water stop is replaced after one 8x10. Prints are fixed in TF-4 and placed in a water hold tray with 4 or 5 dump & fills over 2 hours print session. At the end of the session I selenium tone. Toned prints are rinsed for 5 min before placement into a 10 min HCA bath. Tray wash for 20 min. No stains.
