Ok.
Also, who mixing their Selenium with Hypo Clear? If so, what is your method. I have never tried this method, but Kodak recommends it and I have read where others use it to mix theirs.
Thanks,

Can you point me to a Kodak reference for this? KRST is approximately 60% ammonium thiosulfate IIRC. Why you would mix HCA/sodium sulfite with what is essentially Rapid Fixer is beyond me. I would think mixing them together would kill the activity of both or at least shorten the shelf life.
I always use HCA after KRST to get rid of the thiosulfate.
........... the HCA is exhausted before the toner. Very interesting...
That was Barnbaum's point - there is no point in mixing the toner with HCA. It wastes expensive toner.

Hi Matt:
I seem to recall that the purpose of HCA was to convert the insoluble complex thiosulphate, (ite??) ions into soluble ones that more easily washed out. Could it be that the 'HCA" in the toner inhibits the formation of the insoluble ions from the thio. contained in the toner itself. I'm not a chemist, (as you can no doubt tell) but, if that were the case then mixing fixer with an HCA solution might be a good thing. Or would i just bugger up the whole process
