Q: 10. How can I test my T4 fixer to see if it is exhausted?Can I use my old test solution I used for regular fix?

A: Most cut a small piece of film and if it doesn't clear in a couple of minutes the fix is exhausted. I just throw away the working solution after going through three litres of developer (xtol) or when the solution no longer removes the magenta stain from the film. Not sure what you mean by the second question; I don't think you should mix older working solutions with fresh.
