kallitype fixers

[Colin Graham]

Anyone having any success with ammonium thio fixers for iron based processes? I goofed and ran out of plain hypo just in time for a 4-day weekend....Plenty of 60% ammonium thiosulfate and prefab fixer concentrate on hand though. Any suggestions most appreciated.

Through info on APUG, I understand it's safe to use a 1:9 dilution rapid fixer but with a 1:19 dilution instead.
