RA4 and stop bath
This reply is a long time coming as I have only just joined the site. Most Nova tanks are 3 or 4 slot and using stop bath is worthwhile. It stops dev instantly and avoids contamination of blix and is cheap.

I noticed in this thread that Kodak Supra III was being blamed for problems due probably to age or storage.My experience of Kodak Supra III is totally different as well. I bought a Jobo processor secondhand and the seller gave me Kodak Supra III paper which was then quite old. I only used up the paper a few weeks ago after having it for over a year and could detect no problems with it. It had sat in my darkroom at normal room temp for about a year. The previous owner may have kept it refrigerated but I think not. So my experience is that storage may not be as critical as claimed. Likewise print dev processing time. I have never found this to be critical to the second or even several seconds, having on many occasions inadvertently allowed the Jobo processor to run on before pouring out developer.
Unless you or your print viewers are very critical or can judge prints to a degree that eludes me and my viewers then processing is less critical is supposed. The only exception to that I have found is that print exposure is quite critical but an enlarger timer and colour analyser takes care of accuracy in that area.
