I have always used Kodak Rapid Fix, which is Ammonium Thiosulfate, and I have
always bought it in the 5 gallon cubitaner that makes 25 gallons of fix. In
the last couple of years it has gotten really hard to get and I have to order
it shipped in. I would love to know a cheap and easy source for the Ammonium
thiosulfate.
