Stock Kodafix for paper?

[mph]

I'm currently using Kodafix rapid fixer for film and paper. The instructions say you should use the stock solution at full strength for film and diluted 1:1 for paper.

I tend to produce few prints in a session, which means I discard a lot of dilute fixer that hasn't been used to its capacity.

Can I use Kodafix on paper (Ilford MG IV RC) at stock strength, and re-use it, like I do for film? Why do the directions tell you to dilute it for paper?

I think you will find that the instructions say to dilute your rapid

fix 1:7 for paper and 1:3 for film. Typically, you are instructed to

fix the paper for longer times. However, some 20 years ago, Ilford

developed a method in which one uses rapid fix at film strength for

only 60 seconds to fix paper. This prevents the paper from absorbing

large quantities of the fix and allows for shorter wash times. This

is the method preferred by most photographers today.

However, there should be no problem with keeping diluted fixer until

you have used it up, whatever dilution you may use.

Yes, unlike developer, fixer can be kept with no problem. Put it in a

coffee jar or somewhere between sessions. Do ensure that you don't

exceed the capacity, which should be stated on the instructions.

Ideally, use a two-bath fixer, but that's another story....

There are a couple of chemicals available that will tell you when the

fixer is exhausted. I just drop a new, shiny penny in. If it turns

silver in a few moments then that batch is exhausted.
