Response to TMX anti-halation; double fix nec. with dev. other than pyro?

Hypo Clearing Agent...Perma Wash, Orbit Bath, homebrew etc.

You can't use an HCA after you've developed film in pyro because it removes the stain. However, with a non-staining developer you don't need to worry about that.

I'm not too sure what you mean by double fix. I _presume_ you mean fixing the film near to forever to try to get rid of the leftover magenta sensitizing dye. If you use HCA, though, you need only fix in non-hardening rapid fix for the usual three to six minutes or so, then treat it in HCA, then wash etc as usual.

If, otoh, you're referring to the sodium metaborate after-fix treatment, that's not fixer, that's just an alkaline bath that helps make the pyro stain. That's not used with anything else.
