Processing 4 rolls of 120s with CPE2

[rustyair]

Hi,

I've been processing two 120s on a 2502 reel with a 2521 multi-tank (CPE-2) and would like to process at least 4 rolls of 120s at the same time but jobo thing is a bit confusing...

1. Do I need a 1520 tank with two 1501 reels? or is it a 1540 tank with two 1501 reels?
2. I've heard that I might have an unevenness problem since the 1501 reel is smaller than 2502. Is it true?
3. How much ml developer and blix do I need for 4 120s? Double it to 600 ml? or more?

Many thanks in advance!

2xxx reels require 2xxx tanks, etc; the 1xxx tanks are smaller diameter.

This is the link you need.

I use a Multitank 5 (2551) with 3 of 2502 to develop 6 rolls at a time; needs about 700mL.

You want the 1540 with 2X 1501 reels if you want to use less chemistry.
You only need 470ml when running 4 rolls in the 1540.

You will not see any difference between 1501 an 2502 reels in processing.
