Thanks Bud.

I ran the tests with Rochester tap water and got 1 minute to clear.

The fix did not smell of ammonia. However, if you use a rinse of still water after development and run TF-5 to near exhaustion, it will smell like ammonia.

If it comes out of the bottle smelling of ammonia, I would contact the Forulary. The pH as mixed is about 6.5.
