The leader clips cleared in 2 min, but the film in the tank did not clear completely in 6 (I knew I was getting toward the end of this liter of fixer and extended the fix time from my usual 4-5 min.)
When ever a pour fixer back in the bottle, I grab a 1 oz measures worth and put in two drops of "hypo-check" if I see any cloudiness, I repeat the fixing with fresh fixer and also replece the bottle of working solution. (actually I mix a mew batch and use it to re-fix the film that is still in the tank).
One of the reasons I tend not to use the "t" series films is that they seem to take twice as long to fix, - when I do use them I often will start with fresh fixer.
