Hey... I've been using some 250mL clear jars for storing Pyrocat HD developer solution A and B and I've had good results with this. I mixed some about 3 months ago and the last of it is still going strong and hasn't oxidized. I'll be using much more of this developer in the future and would like to store it in 1L jugs. I have a bunch of empty 1L photo jugs that are empty and are begging to be used. I estimate that I will have this developer all used in 6 months. Would it be spoiled by this time? If not, what would I expect in terms of it getting weaker over time? Thanks in advance.
