I’ve read a lot of mixed opinions on this so I don’t know if you’ll get a solid yay or nay. I run my rodi which is pretty much identical to yours after my salt based water softener system with zero issue. I run two anion canisters though as I burn through that twice as fast as cation and four times faster than mixed. I have very hard water and I’d rather burn through a little more resin than clog up membranes. It’s kinda a coin toss. Some will say you’ll burn through way more resin after a salt based softener, some say you’ll clog membranes faster before a softener if you have really hard water. My experience was that when I ran the rodi before the softener my output would slow down at around a year as the membranes had scale but the tds was still perfect. Since I’ve been running it after the softener I’m going on two years without a slowdown from clogging membranes. My resin usage has not changed in any measurable way that I have noticed either way. Also I am not familiar with the culligan system, it may not even be salt based (could be coconut shells for all I know) and have zero effect on resin consumption at all.

Edit. There’s a rodi company on here that helps answer these questions @Buckeye Hydro I hope I tagged them right maybe they’ll offer up some advice
