luis_esco Posted March 21, 2018 Share Posted March 21, 2018 I need to develop film with Tmax Developer at dilution 1:4 and the minimum amount of developer is 85cc. I will use the 2520 with Jobo CPP2. Thanks a lot Luis Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted March 21, 2018 Share Posted March 21, 2018 It's twice as much developer than you need according to the tank instructions - here -. Using too little developer would be a bigger mistake. Better too much than too little. Link to comment Share on other sites More sharing options...
luis_esco Posted March 21, 2018 Author Share Posted March 21, 2018 If I follow these instructions for Rotary Agitation, using Tmax developer at dilution 1:4 I can only use 54 ml of developer mixed with 216 ml of water ( = 270 ml of final solution ). Too little developer. Link to comment Share on other sites More sharing options...
akocurek Posted March 21, 2018 Share Posted March 21, 2018 I've forgotten the details, but when I was using a motorized Jobo for processing I often used Rodinal 1:50 for T-max 100. I dumped the developer after half the processing time and poured in a fresh batch to finish. Link to comment Share on other sites More sharing options...

Too little developer. - No. The tank will actually hold much more than 270ml or even 425ml of solution. 270ml is the minimum amount needed for rotary agitation. Any less and the film may not be fully covered. Using more is fine. If you read the PDF instructions I linked to above, you'll see that the tank can hold 1500ml of solution.
