Hi everyone!
I bought an ADOX FX-39 TYP II 500 ml conc. on 24.05.2022 and I stored it in a fresh and dark place, without opening it and waiting to have enough films to develop, and now that I wanted to use it noticed that its color is not anymore clear. It turns a lot darker and on top of the bottle I can see black spots.
Should I use it anyway or not?

Thank you very much

I suggest sending those pictures to Adox and ask for their advice. If the solution has turned bad, then they should replace it free of charge.

By the way, AFAIK, the latest FX39 II is the same as the original version but with more eco-friendly sequestering agents.
