Adox ADOSTOP ECO ストップバス（インジケーター付き） - 5L調製用

Finally, a stop bath that doesn't smell like a vinegar bomb — the citric acid formula is way more pleasant to work with in my darkroom. Mixed up a liter in a few seconds and the indicator turned yellow right on cue, so I knew it was good to go.

The indicator makes it so easy to know exactly when the stopbath is exhausted. I love that it's citric acid based, no more harsh vinegar smell in my darkroom. My negatives have come out noticeably cleaner since switching.

Mixed the whole packet into 5 liters as directed and it works fine, though I wish the indicator were a bit more obvious when the bath is spent. The citric acid base is definitely gentler on the nose than the usual acetic acid vinegar smell, which I appreciate in a small darkroom.
