Hey all - Inherited some vintage Acufine -- in sealed cans, no less. Mixed up a batch and the test rolls turned out great. I'm using it stock - my question: Can I return it to the container and re-use it? I've heard veteran users do this, until negs start to thin slightly, when they simply mix up a new batch. Is this feasible? I'm shooting Tri-X, FWIW. Thanks for any help, I've not used this developer before but like the results and like shooting at EI-1000.
