I have been using about 16ml of Ilford Rapid Fixer per 4x5 sheet of Acros and have just started shooting a lot of TMY-2. I read somewhere a while back that the T-Max films deplete the fixer about twice as fast as other films. So I have been mixing 160ml of fixer concentrate into 640 ml of water and using the solution for either 10 sheets of Acros or 5 sheets of TMY-2. All has been fine.
Now I have started shooting a lot of 8x10 and I am running up against the maximum amount of fluid I can put into my 3005 expert drum (1500 ml). If I stick with my current numbers with the assumption that I need twice as much fixer for TMY-2, I have to use 128 ml of fixer mixed into 512 ml water for a total of 640 ml of solution for each sheet of 8x10. This limits me to only 2 sheets of 8x10 TMY-2 in my drum at a time (2x640 ml=1280 ml) before I run out of volume.
Am I overestimating the amount of Rapid Fixer that I need for each sheet of 8x10 TMY-2? Does TMY-2 really need twice as much fixer or is 25% more just fine?
Any help would be appreciated.
Thanks
