Alternate dilution of chemicals

[BHil]

Hi,
I want to use my stock of undiluted B&W Agfa Neutol and unmixed Agfa Acidofix powder fixer in a continuous paper processing machine in which the processing time in each tank is 100 seconds. The recommended fixing time for use in trays is 5 to 10 minutes, therefore I am curious to find out if by making the fixer more potent, that is by mixing the powder with a lesser quantity of water and by raising the temperature to 30C the fixer will perform its function in the limited 100 seconds ? The temperature but not the running time can be adjusted in the processor.
Does anyone have any experience with this, and is there the risk of any adverse effect?
Cheers
Bert

If you want quicker fixing, use ammonium thiosulfate fixer ("rapid fixers", usually liquid concentrates) instead of sodium thiosulfate (powders). Higher concentration of course makes it quicker but there's a limit with traditional sodium fixer. 100 seconds may be enough but I'd use a rapid ammonium thiosulfate fix.
