I put the paper in the fixer, for the first 3 seconds it stays the same tones as when it came out of the developer and stop. Then for the next 6 seconds the darks of the paper get darker and the lighter parts get a tiny but grayer, but not as much as the darks change, then it stays the same for the remainder of the 1:30 fix time.
It retested all the time and such, for the new paper.
Yes the safelight is closer to the developer then the fixer but I did take that into consideration.
PE- I mixed up some stop bath and will see if that helps.
