I have never had a problem with the chinese amidol...just use an EXTRA tray of water after the fix to let the print mellow out...after the next print is made I transfer to a larger bucket and so forth...my chemical supplier friend gave me a wonderful fine mesh screen that I use to filter the chinese stuff-works like dream but for the life of me I can't figure out the info to post here (sorry bout that!!) where there is a will there is way
Best, Peter
