Champion Amfix 2x5L Fixer

I’ve been using this fixer for both film and paper, and it handles rolls of 120 with no issues. The 2x5L concentrate lasts me months even with heavy printing sessions.

The concentrate mixed up clear and I’ve been using it for both film and prints without touching the working solution again. Stability on the shelf is exactly as advertised for my sporadic darkroom days, and the two 5L bottles will last me ages.

This fixer concentrate keeps for months after opening, which is a huge plus for someone like me who doesn't process film every week. Cleared a roll of Tri-X in under three minutes with no issues.
