PROFESSIONAL 200 濕潤劑，16 盎司濃縮液

Noticed right away how easily it flows off the film instead of beading up, which was my biggest issue before. A tiny capful in the final rinse is all it takes, and the 16 oz. concentrate will last me forever. My negatives come out of the tank streak-free every single time now.

The little squeeze bottle dispenses just a couple drops per tank, and that’s all it takes to get the water to sheet off my negatives without leaving any tidal marks. My last roll of 120 dried spotless, even in hard water conditions. Definitely earning its spot in my darkroom routine.

A tiny drop goes a long way in my final rinse, and I haven't seen a single water spot since I started using it. The concentrate is easy to measure out, and it's cut down my drying time considerably. My negatives come out perfectly clean every time now.
