Hi everybody, can anybody help. I've searched for this and finding little or nothing.

I'm using a Jobo CPE 2 with 1520 Unitank for my 120 films and a 2523 for 4x5. I split the tetenal kit into 2 x 500ml batches for the 3 bath bottles. I process single roll at a time in the 1520 and 6 sheets in the 2523. The problem I have is both tanks only require 240ml & 270ml for processing and I am not sure of the yield. After the first run on fresh solutions, it means pouring used back into fresh solution, hence calculating the yield. I'm also unsure when the FD is no longer usable. I've read that it is the FD that goes in Tetenal.

I'm also unsure which times are best. Some say the Fuji times for 3 bath are ok to use for Tetenal but they are quite different to Tetenal's and Jobo's. I've been using Jobo's times for Fuji films as per 7.30m (FD) 4m (CD) 6m (BLX) and this seems ok but not sure if these are best for longevity.

So, what I've now done is I've mixed up 270ml solution but I'm at a bit of a crossroads and am looking for help.

1. What are the best processing times for this amount of working solution. What are the additional plus any additional time for 2nd, 3rd roll.

2. What are the additional times for this quantity of solutions?

3. What yield can I expect? Will I get 3 rolls, 4 rolls, 5 etc.?

4. How will I know when the FD is finished?

As always, many thanks in advance for your help.
