Paul,

I use HCA at normal working strength (1:4) most of the time (FAEW paper). It
clears just fine, so no need to use it stronger.

You're welcome!
Kerik

Thanks, Kerik...

I use citric as my first bath, and HCA as the next two. I don't really have 
any reason to replace the HCA except for curiousity  and/or cost 
considerations, which really aren't considerations at all.

Do you use HCA at standard film 1:4 or another dilution? I think Stan Klimek

mentions 1:1 in the Arentz appendix?

I usually use 1:3 - 1:4-ish and the prints clear just fine...

Much thanks for your reply and knowledge, as always...

Paul
