I am considering purchasing a Jobo CPE-2+, and I am trying to estimate the C-41 chemical costs. The main reason, I want to process my own film is that it sounds like fun. However, I am confused about reusing the Bleach.

Assuming I purchase the 1 gallon Kodak Flexicolor kit, and I use the Jobo Tank 1510 with a single 35mm reel, the tank requires 140 ml of chemistry as listed on the Jobo site. Therefore, I should be able to process (27) rolls of film or 3.8 l / .140 l.

On the Kodak Flexicolor site, they specifically address rototary processors in the following file. http://www.kodak.com/global/plugins/...ls/z131_03.pdf

Kodak says the bleach can be reused, and the maximum number of 400 ASA rolls should be (28) or twice the "sink-line" developer rate of (14) -- see table 3-3.

The obvious answer is -- Don't re-use the bleach. However, the bleach is the most expensive chemical, and reusing it will drop the cost per roll.

Does anyone reuse the bleach, and if so, how often?

Thanks,
Rich
