Chemical Change - Color

[lazal]

Hello, I have a problem , we clean the lab and change the chemicals but after we put new solution on it the test has a cyan tint even on unexposed part. (attachement).What could be the problem? Thnaks.

Cyan whites usually point to CD contamination, or possibly no/not enough (paper) developer starter added.

If you did mix the CD tank solution together with paper starter as recommended by your chemical manufacturer, it will probably be contamination, maybe the containers you mixed with were not clean.

If so drain out the CD tank solution, fill the tank with water, run the machine for 5 minutes, drain out the water and then mix fresh CD tank solution with starter making sure every container is clean.
