Blix does have a long shelf life even after mixing. I have found that it will take on a milky appearance when it has 'gone off' or is exhausted and has a noticeable change in smell too. So if it is still a deep burgundy colour, with no milky appearance it should be OK. If what you have is in a bottle it should be shaken vigorously before using.
I use a Nova deep tank processor and yesterday I drained the 3 slots and washed them out. The BLIX was still clear and active but there was a thick layer of sulphate at the bottom, deposited during the life of the solution even after regular replenishment. The dev & stop bath were OK, but full of tar and after cleaning, the solutions were simply poured back in and topped up.
