Thanks everyone for your help, including Ian C for the message you sent me. I now realize that it is implicit that any wash step must have water changes. I ran a new set of rolls today in the Jobo and did 6 changes of water (4 x 30sec and 2 x 1min) and there was not really any noticeable coloration of the final rinse bath (done in a glass beaker) and my negatives are no longer bleeding red water onto the floor of my shower as they dry.

The first batch scanned fine, but I am thinking I should probably rewash and re-stablize them for archival purposes. It seems from other threads on here that that can be done, just as it can with black and white negatives.

Thanks for your help!
