The Pattersons require 10oz to cover one roll of 35mm and 17.5 oz for a roll of 120 or 220. If you have 5 35mm rolls in a 5 roll Patterson tank, you need 10 oz of solution for each - 50 oz. HC-110 dilution B, for example, is strong enough to develop several rolls of 35mm. Dilute solutions such as Rodinal 25-1 and others are not. Randolph
