Right, just mix it 1:25, 50, 100.. whatever and use as a one shot developer. I have been using the same bottle for about 6 months and am about half way through. With the exception of Kodak HC-110, you will not find a cheaper way to develop film. At least with a manufactured product.
It lasts seemingly forever after the bottle is opened...one of its endearing qualities. Even when the developer is rust coloured or darker, it works fine.
