Chloride can be a restrainer for some color papers as they are made from AgCl (Silver Chloride) emulsions. In any event, Chloride does tweak the curves a bit.

You can use RA-RT Dev-Replenisher without the starter. I do all the time. I use 2' at 68F in a tray or 1' at 100F in a drum. In the drum, I always use a prewet. I also use a stop with the drum but not with trays. The stop insures uniformity and low Dmin.

This is all with EK chemistry and paper. I have reports that Fuji CA does not behave as well with these conditions, especially at lower temps.
